There was a drummer joke going around back in the 60s:
A letter, addressed "To the world's greatest drummer" arrives at the home of Louie Bellson.
He takes one look at it, and says, "well, this is obviously not for me," and forwards it to Gene Krupa.
Krupa also takes one look at it and says, "well, this is obviously not for me," and he forwards it as well.
The letter makes the rounds of famous drummers' homes, until it finally winds up at the home of Buddy Rich.
Buddy takes one look at it, and says, "well, this is obviously for me," rips it open, and reads:
"Dear Ringo...."
