Duffus Mcclutski had a little tool shed in back of his farm. But being that there were no windows and the transformer that ran the lights got fried when Duffus tried to curl his hair to impress the cute girl next door, Duffus was always cutting himself on his sharp tools whenever he went to retrieve them from his tool shed to use.

So one day Duffus had an idea so that he would never cut himself again. He got 10 candles, a pot, and a blow torch. His idea worked rather well, too.

Duffus didn’t use the candles or the torch for light as most people would; no he did something quite different to keep from cutting himself.

What did Duffus do?

Hint:

He did what many industrial saw blade manufacturers do.

Answer:

Duffus melted the wax and dipped the tools in it to cover the cutting edge. Industrial suppliers of saw blades and cutting equipment use a similar method to coat and protect sharp edges. When the item is first used, the wax simply peels off. Then when finished with the blade he can simply reapply the wax.

You are on an island and you see a forest person ploughing a field with a large tractor. There are no bridges or tunnels to the island and you wonder how the tractor got out to the island.

“ That’s a good question,” says a nearby forest person, reading your mind. “ I have the only boat around here and it’s not big enough to carry that tractor over. I didn’t drop off any parts, either, so he could n’t have built it there. And no one has an airplane or helicopter to drop it off.”

So how did the tractor get on the island?

Notes:

1.the tractor was not built on the island

2.even with tides, the water is too deep to drive across

3.it was not driven across the bottom of the ocean or under water

4.it was not disassembled

Answer:

There are several answers to this riddle.

1.He drove across the frozen water to the island.

2. Maybe the land only recently became an island. It could have become so due to flooding of the land around it, either by nature or intervention by man. The tractor could have been driven there prior to the flooding.

3.With overinflated tyres it floated across.

You are visiting an island on which two tribes of natives live. One tribe has black soles and always lies; the other tribe has white soles and always tells the truth. There are three natives standing near you. You can’t see the bottoms of their feet, and indeed you find out it is extremely rude to look at another’s soles, but you are curious so you ask the first man,

“ Sir, what colour are your soles?”

Now he happens to understand English, but he can’t speak it, so he replies in his native tongue, “ Glub Glub.” You turn to the second man and ask, “ Sir, what did he say?” The second man replies, “ He said he has white soles.” Now to be sure, you turn to the third and ask, “ Sir, what colour soles does this second man have? ” The third man replies, “ Sir, he has black soles.” Now the question is, what colour are the third native’s soles?

Answer:

Enve though you do not know the native language, you know what the first native said. If his soles were black, he lied and said they were white. Either way, he said they were white. Since the second native confirmed that the first said his soles were white, the second native told the truth and thus had white soles. The third native lied in claiming that the second had black soles, so the third native had black soles.

Mr Waters and her twins, Danny and Anny, want to cross from the east side of the river to the west side in a canoe. But the canoe can hold no more than 200 pounds. Ms Waters weighs 160 pounds, and Danny and Anny weigh 100 pounds each.

How can all three of them reach the other side of the river in the canoe?

Answer:

First the twins paddle to the west side of the river. Anny stays on the west side, and Danny comes back. Mrs Waters rows alone to the west side, leaving Danny on the east side. Finally, Anny comes back for Danny.

Together, they paddle to the west side of the river. ( You can reverse Anny and Danny—it doesn’t matter which one goes first.)

One day, a great scientist gone bad decides to wreak havoc on others in his profession. He has another scientist kidnapped, uses an evil formula that disables 4 of the good scientist’s five senses: his sight, his smell, his taste, and his sense of touch. He then has him strapped to a bed very securely. He then says, “ I am going to place a single object in the center of this room with you. If you want to live, you will have something to tell me about the object when I return. Please do not insult my intelligence by telling me that it is an object, or an object that I placed in the room, or anything having to do with me, or the object’s location for that matter. We both know it is an object, that I put it here, and that it is in the center of the room. You must therefore state a SCIENTIFIC FACT about the object.” Before leaving, though, he says, “ Silly me, I almost forgot……” ( He then disables the good scientists hearing. Now he has none of his senses to work with.) He returns after one hour, restores all of the scientist’s senses, and says: “ So tell me something about the object, professor.”The good scientist saves his own life with his answer, to the chagrin of the evil scientist. What, though, could he have possibly said, being that he had no senses?

Answer:

The good scientist simply said: “ It is a SCIENTIFIC FACT that the object you placed in the center of the room with me has MASS.” All OBJECTS have mass.

The master’s family is moving to a new house. They have a dog, a cat, and a pet mouse, but the animals don’t get along in the car, so they can take only one at a time. Then there are other problems. They can’t leave the dog alone with the cat, because the dog chases the cat if no one is watching.

At a local bar, three friends, Mr Green, Mr Red and Mr Blue, were having a drink. One man was wearing a red suit; one a green suit; and the other a blue suit. “ Have you noticed,” said the man in the blue suit, “ that although our suits have colors corresponding to our names, not one of us is wearing a suit that matches our own names? ” Mr Red looked at the other two and said, “ You’re absolutely correct.” What color suit is each man wearing?

Answer :

Since none of the men are wearing the color of suit that corresponds to their names, and Mr Red was replying to the man in the blue suit, it had to be Mr Green to whom he replied. We then know that Mr Green is wearing a blue suit. Therefore, Mr Red is wearing a green suit and Mr Blue is wearing a red suit.

A man dies and arrives at the Pearly Gates of Heaven. He finds himself in a long corridor with two doors, and he knows that one leads to Heaven and one leads to Hell. However, he doesn’t know which is which! Sitting next to these two doors, at either end of the corridor, are two men: the truthful man and the liar. The liar is not deceitful, because he can’t help but lie when asked a question. However, they look identical and he cannot tell which one is the liar and which one the truthful man. To find out which is the door to heaven, he can ask either the man on the left or the man on the right just one question! How did he ask the question?

Answer:

You ask either man, “ Which door would HE ( pointing to the other man ) say leads to Heaven?” and then you take the opposite door to the one he says.

The King is about to die. He sends messengers throughout the land looking for the three smartest people. Finally, three are found. He gives them a task to see which one is the wisest. He tells them, “ I will seat you in a triangle so that each of you faces the other two. Then I will blindfold you and paint either a yellow or a blue dot on each of your foreheads. When I remove the blindfolds you must each raise your hand if you see any yellow dots. As soon as you have worked out what colour your own dot is, lower your hand and tell me.” So he seats them, blindfolds them, and then paints a yellow dot on all three foreheads. When the blindfolds are removed, all three hands go up. After a long pause, one hand comes down and the man says, “ Your Highness, I have a yellow dot.” How did he know?

Answer:

The blindfolds are removed, all three hands go up. This can only happen if at least two people have yellow dots or if all people have yellow dots. The man sees 2 yellow dots, so he raises his hand, and sees that the other 2 have raised theirs. If he had a blue dot on his head, one of the other men would quickly figure out that he himself had a yellow dot. Since everyone sits there looking confused, and because our hero knows that the other 2 are wise men, too, he deduces that his dot must be yellow.
