Two blondes were recently observed in a parking lot trying to unlock the door of their Mercedes with a coat hanger. Here is their dialogue:
Blonde One: I can't seem to get this door unlocked!
Blonde Two: Well, you'd better hurry up and try harder! it's starting to rain, and the top is down!
Blonde One: I can't seem to get this door unlocked!
