Back when we were in high school, we used to do this thing called the Chinese Fire Drill. What you do is pull up to a stop sign and everyone in the vehilce gets out and goes to the opposite side of the car and re-enters the vehicle from that side. The idea behind this prank is to hold up the car behind you and make them wait while you and your passengers are securing different riding positions in the vehicle. Yes, I realize this is childish but most people who do this are under the age of 21. Subaru recently came out with a series of new commercials featuring dogs driving their vehicles in different scenarios. here's one of my favorite where the dogs do a Chinese Fire drill.
