A blonde is driving along a deserted country road with fields on either side. She looks out the window and sees another blonde in the middle of a field, in a rowboat, rowing and rowing.
She stops the car, rolls down the window and yells, "You know it's blondes like you who give the rest of us blondes a bad name!"
Getting no reaction from the blonde in the rowboat, she screams, "If I could swim I'd come out there and punch you out!"
