Not exactly a game story but pretty funny anyway:
A friend was pretty new to the sport and had never played tournaments before so I acted as a sort of mentor (poor guy...)
A couple of weeks before a tournament he calls me and asks for some advice. The discussion comes to things he needs to bring along:
"In tournament you need one of those... buttplugs, right?"
After laughing, I explain that I believe many paintballers use them but they are not necessary. It could improve the game though, I'm not sure. Barrels plugs, on the other hand, should be used.
