Pranking Ex-Wife

A guy calls up his ex-wife and, disguising his voice, asks to speak to himself.
“Sorry, he doesn’t live here anymore, we’re divorced!” comes the response.
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?” yells bac the angered ex-wife.
“Oh, I know! I just can’t hear it enough!” says the guy before hanging up.
