No joke here... One time we played a team who had two short Asian guys who would constantly foot fault no matter what. It's how their service motion was. And the foot fault was in by a good 6 inches or so. I laughed at the match, which we lost, but told them that if they make it to state they'd lose their *** for all the foot faults their doing. They disagreed. Fast forward to the end of that season and them making it to state and losing every single match they played.
Turns out, people were getting ticked with it during matches and called in officials to make the calls. Foot fault city.
