3 patients are about to be released from a mental asylum, but as a final test the director ask them each at the time in his office, all three are waiting outside his office when he calls the first one in.

"I need you to jump trough that doors key-hole" commands the director. So the first one starts running and slams into the door. The director tells him hes not ready to be released yet. When he leaves the office the other 2 ask "and?" but the first one shakes his head "I'm not released".

The second goes in and is commanded the same, he studies the door first, counts his steps runs and jumps head first into the door. He also goes outside shaking his head, "me neither <img src="/ubbthreads/images/graemlins/disagree.gif" alt="" />"

Now the third one, goes inside and very little later comes outside smiling, "I'm out of here!!!" , But the other two ask "HOW???". "Well," said the third "You can't jump through that key-hole, I told him".
"But why not?" asked the other 2 puzzled, where the third replies "It's quite obvious why... the key was still on it".

It's one of these days...
