Imitate Jokes

A young man was attending an audition being held for potential guests on a TV talk show.
"What is it that you do?" the show's producer asked the young man.
"I imitate birds," the young man proudly replied.
"Oh, please," grumbled the producer. "People who imitate birds are a dime a dozen. I'm sorry, we can't use you."
"Fine," replied the disappointed young man, as he flapped his arms and flew out the window.
