I'm bored. So here goes...
=====
Four friends, happily named A, B, C and D, were taking a lovely stroll in the jungle one day, when they were captured by some evil person and buried up to their heads in sand, like so: (ph34r my ms paint skillz:)
They were buried in a line, with A behind a wall which nobody can see over or around. Each of them was facing toward the wall. They were told that they were not allowed to communicate in any way, or they would be shot. They were told that they could not move their heads in any way, or they would be shot.
To add to the bewilderment, said evil person produced four coloured hats. Two were red, and two were green. He then placed on on the head of each of the four captives in a random order. None of them could see which hat was on their own head. He then told them that they would be shot unless one of them could correctly guess the colour of their own hat.
Judging by the arrangement in my lovely little picture:
Sooo... the question is: which one of them would be able to tell which colour hat they were wearing and save them all from a certain death?
karma for the winner!
edit: explain your answer! like in an exam

Judging by the arrangement in my lovely little picture:
- A can only see the wall
- B can only see the wall
- C can see B only
- D can see B and C
- A does not have x-ray vision and therefore cannot see the others' hats.
