Nothing. Drunks, idiots, the ill-mannered, the clueless, whatever, will always be with us. That having been said, I suppose the TV commentators could make negative remarks when that sort of noise intrudes -- that is, make fun of or comment on the behavior. They do that sometimes for really egregious behavior. However, I doubt they'd take on the occasional "get in the hole" or "you da man" for fear of offending a significant portion of their viewers and being accused of trying to "take the fun out of it."
