Punchline of the Day: And what, quit show business?

And what, quit show business?--the punchline to the old elephant joke. To be said when doing a really  disgusting task.
Here's the joke:
A man who spent 25 years scooping up the elephant poop at the circus was complaining about his disgusting job. "I hate my job, I can't take it anymore," he said vehemently.
"Why don't you find another job?" said the friend.
Shocked, the man responded, "And what, quit show business?"
