A blond is driving down a country road. She looks over to the right, and sees another blond, in a row boat, out in the middle of a field, rowing.
The first blond can't believe her eyes, stops the car, and gets out to look at the blond in the rowboat. The longer she looks, the madder she gets.
Finally she says: "You know, it's blondes like you that give the rest of us a bad name. You're just sitting in the middle of a field in a row boat rowing. That's so stupid! If I could swim, I'd come out there and kick your ass!"
