Blonde Joke

I usually find blonde jokes pretty stupid - not funny. However, my grandfather sent this one along today and I did enjoy it. So I've decided to share.

A blonde pushes her BMW into a gas station. She tells the mechanic it died.

After he works on it for a few minutes, it is idling smoothly. She says, "What's the story?" He replies, "Just crap in the carburetor."

She asks, "How often do I have to do that?"
