Twelve Inch Radio Joke

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.
