Man calls home.
Maid answers phone.
He says, "Can I speak to my wife?"
She says, "No, she's upstairs in bed with her boyfriend."
He says, "Ok, go to the hall closet and take out my shotgun. Go upstairs and kill them both."
Being the loyal maid, she says, "Ok."
5 minutes later she picks up the phone and says, "Ok, they're both dead. What should I do with the bodies?"
He says, "Throw them in the pool, and I'll take care of them when I get home."
She says, "We don't have a pool."
He asks, "Is this 555-1234?"
