A man walks into a bar, does a somersault and lands on a bar stool.
"How do you do that?" asks the bartender.
"I work in the circus," answers the man.
A few minutes later another man comes in, does double somersault and lands on bar stool.
"I bet you work in the circus, too?" says the bartender.
"Yes, I work with him" answers the man.
A little later another man comes in, does a triple somersault and lands on a bar stool.
"Ho, you too work with them in the circus?" asks the bar tender.
"No, I tripped over the doormat!" answers the man.
