Hit job

I'm a hit man for the mob, and I got a pretty blonde for a wife. She's the prettiest thing, but she can be dumb as a rock sometimes. Once in a while, I'll ask her to do some of my dirty work for me. So I asks her one time, "Hey sweets, here's the info on this dame I need you to knock off. Could you do that for me?" She says, "Sure thing, baby." She leaves and I don't see her again for a couple weeks. She gets home and I asks her, "So, honey sweets, did you finally knock off that dame?" She says, "I'm tryin', baby, but I'm still gonna need more time." She leaves again for another couple weeks, but she comes back and it's the same story. For a few months, it goes like this, until finally I says, "This is taking you too long, sweets. What's the problem here?" She says, "Believe me, baby, I'm tryin' real hard. Every night, I'm at her place tryin' to knock her off, but she just ain't gettin' pregnant."
