A man walks into a bar with a empty jar and a donkey. He says "Pay me a dollar, and try to make my donkey laugh. If you can make him laugh you can have the money in this jar". The best of the best cam and no one could make the donkey laugh. The jar was full and a stranger walks in and say "I can make your donkey laugh". He puts a dollar in the jar, goes in the room, and a few minuets later the donkey is laughing very loud."
The stranger comes out and the man gives him the jar of money. The man asks the stranger how he did it. The stranger refuses to tell him

Later the same man brings the donkey back in the bar with a jar. He says "Pay me a dollar, try to make my donkey cry. If you make him cry the money in the jar is yours."

The best of the best come and yet no one can make the donkey cry. The same stranger walks in and puts a dollar in the jar. He goes in the room and makes the donkey cry. When he comes out the man says"You must tell me how you made my donkey laugh and cry" The stranger says "Well I made your donkey laugh when I told him I had a bigger **** then him. I made him cry when I showed it to him"
