A guy walked into a bar one day and noticed a jar full of money on the counter. He asked the bartender what it was for and the bartender replied that if he could go into the back and make the donkey laugh, he could have that jar of money.

So the guy walks in the back and a few minutes he comes out with the donkey laughing his head off. He gets his money and walks out.

The next day the same guy went to the same bar and noticed another jar of money sittin on the counter. The bartender, when asked, said that if he could go in the back and make the donkey cry, he could have that jar of money.

So the guy goes in the back and about 5 minutes later comes out with the donkey crying huge tears.

As the guy was about to leave, the bartender stopped him and asked him how he made the donkey laugh and cry.

The guy replied: The first time I told him I had a bigger dick then he did, and the second time I proved it.
