Many ago I watched a guy fill another racers offroad vehicles belt drive transmission with Doritos.
As I recall, it escalated pretty harshly, and finally ended up with one guys pit box beind completely CA'd shut, every door, every lid, everything, and the other guys $300 sunglasses glued to the tent...
Got pretty cruel at the end, and those guys were not the best of freinds for a while. So be careful.
