My wife was complaining I fart too much, so she ripped a big one right back at me. I asked her, "Honey, you never did that when we were dating. How come?"
She said, "'Cause I didn't get an asshole till we were married."
When her car conks out the old lady pushes it into a gas station. Soon the mechanic has it purring like a kitten. The old gal asks: "What's up?" He tells her: "Crap in the carburetor." She says: "How often do I have to do that?"
