I think the lamest jokes are always those that are translated from another language, so here goes, a moroccan joke:
Lol so much better in Moroccan though.A mental asylum was getting too full, so in order to make spaces they decided to release some patients. Not wanting to relaease any ones who were truly crazy, they devised a test for the patients. gathering them all the doctors drew a door on the wall with a handle and said to the patients "You are all free to go" and stood back to observe. In a surge they all flew forward slamming themselves against the wall only to get up and try yet again to barge for this imaginary door. All except one guy who stood back, leaning against a post and watching with amusement on his face.
The doctors were pleased, this man was obviously sane, as he had not tried to use the fake door. One doctor goes over and says "sir, you are free, why do you not run to the door with the others" the man giggled and turned to the doctor "They are all crazy as I have the key"
