Had a HS rec game once while working with The Immortal Dave. One girl intentionally scratched the other in the face (not kidding). The other girl then slapped the first one across the face. Dave tossed the first one and gave the second one just an intentional foul.
When I asked him about it, he said he was invoking the "chickfight rule".
I asked him if that rule was in the rulebook. He said it was in his.
