Hi all,

After looking at Netnerd's optical illusion thread I've decided to start a logical and lateral thinking thread where we can post questions which may have no answer when in true fact the answer is quite simple.

The main idea is to come up with the most difficult problem. Don't LOOK UP answers ON THE internet because IT ONLY spoils THE FUN

I'll start things off:

A new prison has been built in the middle of a vast lake. One morning, it's discovered that a prisoner who can't swim has escaped. The only evidence he leaves behind is a strand of shoelace how did he do it?

Enjoy

A woman stopped her car outside a block of hotels and immediately knew she was bankrupt. Why?

A man leaves hospital and begins to walk home. On his journey he passes a phone box which begins to ring. Instead of answering it, he punches the air and runs all the way home cheering. Why?

Netnerd again correct gees gotta' think up harder ones

There are 4 boxes. One is stuffed full of cash, the other 3 are empty.

You get to choose one box, which remains unopened for now.

After choosing your box, I then reveal to you the contents of two of the other boxes, which are both empty.

We are left then, with the box you chose, and one other box.

I offer you the chance to swap.

What do you do? Swap boxes, or remain with your original choice?

New one to get us going

Acting on an anonymous phone call, the police raid a house to arrest a suspected murderer. They don't know what he looks like but they know his name is John and that he is inside the house. The police bust in on a carpenter, a lorry driver, a mechanic and a fireman all playing poker. Without hesitation or communication of any kind, they immediately arrest the fireman. How do they know they've got their man?

- In a street there are five houses, painted five different colors.

- In each house lives a person of different nationality.

- These five homeowners each drink a different kind of beverage, smoke different brand of cigar and keep a different pet.

Who owns the Fish?

1. The British man lives in a red house.
2. The Swedish man keeps dogs as pets.
3. The Danish man drinks tea.
4. The Green house is next to, and on the left of the White house.
5. The owner of the Green house drinks coffee.
6. The person who smokes Pall Mall rears birds.
7. The owner of the Yellow house smokes Dunhill.
8. The man living in the center house drinks milk.
9. The Norwegian lives in the first house.
10. The man who smokes Blends lives next to the one who keeps cats.
11. The man who keeps horses lives next to the man who smokes Dunhill.
12. The man who smokes Blue Master drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to the blue house.
15. The Blends smoker lives next to the one who drinks water.

This is it! Good luck

A cowboy rides into town on a Monday. He stays at the town for three days, then leaves on Friday. How did he do it?

Here is a though one.... Which came first? The chicken or the egg?

You are tricked into a doorless and windowless room on all 4 sides, including top and bottom. The only things inside the room are you, a mirror, and a wooden table. How do you escape?

You are put into a prison that has two doors. One leads to freedom, the other to certain death. Inside the prison, there are two computers: one that always tells the truth, and another that always tells lies. You do not know which computer is the liar and which is the truthful one, but you are allowed to ask only one question to one of the two in order to go free. What question do you ask, and to which computer do you ask it?
