Here is one of the older sliding puzzles:

You have a sliding puzzle that looks like this:

AB
 C
DE

You may move a block with a letter on it to the blank space by sliding it there. How many moves does it take to put D where E is and E where D is at the same time? (The other pieces don't need to be in their original spots.)

(In reply to re: 10 moves! by Nosher)

I know! :-) I wanted to give the best answer and was hoping nobody would notice that!
