Circus

A man decides to join the circus. He shows up to demonstrate his
skills to the impresario.

"I have the most unusual act," he announces. "I'm sure it will amaze
you."

He proceeds to climb a tall tower, and jumps off. He flaps his arms
wildly, and finally his fall slows. He soars forward, then swoops
upward, turns and swoops back again. Finally he stops in mid air and
gently lowers himself to the ground.

The impresario stares blankly at him for a long time. Finally he says,
"Is that all you've got? Bird imitations?"
