A guy walked into a bar and the bartender said if you can make my donkey laugh you get all the money in the jar, but it costs $1 to try. The man agrees and puts $1 in the jar. He goes around the counter and whispers something in the donkey's ear. The donkey immediately starts laughing really hard. So the man takes the jar with all the money and leaves the bar. A couple of months later the man comes back to the bar and the bartender says if you can make my donkey cry you get all the money in the jar, but it costs $1 to try. The man agrees and puts $1 in the jar. The man goes around the counter and does something the bartender can't see. The donkey immediately starts crying really hard. The man takes the jar and is about to leave when the bartender stops him and says "Can I ask you a question". The man says "sure". So the bartender says "how did you make my donkey laugh the last time". The man says "I bet him my penis is bigger than his". Then the bartender says "Then how did you make him cry". The man says "I showed him".
