Bachelor Blake had a telephone problem last summer. Some dude who
works a night shift apparently has a phone number almost identical to
Blake's.
Starting around midnight, he'd phone every hour and say, "Hey,
what're you doing there, Mister? Where's my wife?"
Blake'd reply, "You have the wrong number."
The man would snarl suspiciously, "Yeah, I'll bet!" cuss a short streak,
and hang up.
Blake put up with this abuse for exactly three nights. On the fourth
night, when the called and asked, "Hey, what're you doing...," Blake 
interrupted in a frantic screech, "For Pete's sake, call the cops! My wife 
followed me here, she's chasing your wife with an axe, and she's gonna... 
HONEY, DON'T...ARGGGGH!"
The man hollered, "What happened? What? Are you there? Hold on, I'll send 
the police!" The phone clicked, the dial tone came on, and Blake hasn't 
been bothered by night calls since.
