Neat joke. The word "Mature" in your subject heading reminds me of this -- one of the funniest things I ever heard (!!??).

Victor Mature had retired from movie making. His consuming interest then (and before) was playing golf. He wanted to join a famous golf club near him, but the club had rules prohibiting actors as members. Upon hearing that, Mature said:
"I'm no actor, and I've got 64 pictures to prove it."
