Ok i got one,

There 50 ugly people and God says that he will grant them all one wish...

They stand in a line and God asks the first person what is your wish he says make me good looking, and he does...

The person at the end of the line is laughing his head of he cant stop!

God asks the second person the same question and he answers the same 'make me good looking' and he does....

The person at the end of the line is still laughing but nobody knows why...

This goes on and on everyone asks for the same thing until eventually God comes up to the last person and says 'What do you wish for' and the ugly person says 'Make them all ugly again'.... haha i thought this was funny i heard it when i was stoned and found it hilarious
