Every morning for 15 years, Martha says, "One of these days, you're gonna fart your guts out!"

One Thanksgiving morning, Martha's preparing the turkey and gets an idea. Before her husband gets up, she creeps upstairs and places the turkey innards in his pajama bottoms, giggling to herself.

Well, later that morning, Bob wakes up and goes through his morning ritual. He screams as he goes running into the bathroom. Martha laughs, but is concerned after noticing that Bob has been in the bathroom for 3 hours.

She runs upstairs, and is about to knock on the door, when Bob opens up, pale as a ghost. He says, "You were right. You were right. I did fart my guts out, but by the grace of God and these two fingers I got them back up there again."
