Singer: Knock knock
Drummer: Who's there?
Singer: We don't want a drummer
Drummer: We don't want a drummer who?
Singer: We don't want a drummer who has no sense of rhythm!

Singer: We have decided that we no longer want you in the band.
Drummer: Okay.
Singer: Now, I know this is your house, but do you mind pissing off for about half an hour, we've got a practice session to finish!

Singer: Do you want to hear a joke?
Drummer: Go on then.
Singer: What happened to the drummer that never practiced?
Drummer: I don't know!
Singer: We sacked you!
