Craziest/Dumbest/Most Outrageous thing you've done in a car.

[Shoe]

The dumbest thing I have done was not asking a girl for road head.

We are driving back home (about an hour drive), and she asked, "is there ANYTHING i can do to help keep you awake?" (she asked this several times) My response each time was just, "No, I'm fine." As opposed to implying that road head would keep me awake, which is what she was actaully implying at the time.
