A guy calls up his ex-wife and, disguising his voice, asks to speak to
"Sorry, he doesn't live here anymore, we're divorced!"
Next day, the guy does the same thing with the same results.
He does this everyday for a week, and finally his ex-wife realizes who
it is that keeps calling. "Look, Bozo! We're divorced! Finito! End of
story! When are you going to get that through your fat head?"
"Oh, I know! I just can't hear it enough!"
