A man goes to the circus manager and asks for a job. The manger asks "What can you do?" "Well," says the guy, "it's easier if I show you." He starts flapping his arms, and runs then he takes off and flies around and around inside the big top, looping around the poles, perching on the high wire and eventually he swoops back to the manager and lands softly in front of him. The manager looks at him for a minute, strokes his chin and says "That's all you do? Bird impersonations?"
