I was always the guy working on his car and installing stuff in High School. A friend(who was not in to cars, at all) once asked what a button on the dash in the passenger side did.

Straight face, no emotion, I explained that I had installed a homemade injector seat, but put the control as far away from me as possible to keep from accidentally sending my passenger flying out of the car. He bought it, hook, line, and sinker. He then screamed bloody murder when I reached over and opened the glove box.

Hadn’t thought about that story in YEARS.
