A circus is holding auditions and a 91 year old man shows up. "What do you do?" asks the ringmaster.
"I bend over backwards," says the man, "and pick up a handkerchief off the floor with my teeth."
"Wow," says the ringmaster, impressed that this elderly man is agile enough to do this. "Then what do you do?" he asks.
"Then I bend over again," says the man, "and pick up my teeth."
