This is called "The End of Comedy."
"Joe: you should do a vaudeville review.
Bill: but there are no stand-up comics like Mighty Head
anymore.
Enter Mighty Head.
Mighty Head: give me a light, boys, for I want to smoke.
Hey bob-a-rebob, fellas, how about a little joke?
Joe: OK.
Mighty Head, will you act in a play for us?
Mighty Head: now I'm too old for that and too famous for that.
I'm just my whole life, one big joke, ain't that enough?
He acts crazy.
Hack, hack, hack, hack, hack.
Bill: yes, Mighty Head, that is enough.
He's amazing."
