A guy calls into a radio station and he says he has a joke for the DJ. The DJ goes, Alright, let's hear it.
The guy goes, What has a 2 inch penis and hangs down?
The DJ says, I dunno, what?
The guy says, A bat. What has a 12 inch penis and hangs up?
The DJ replies, I dunno, what? Next thing the DJ hears is a dial tone.
