Ah, quit trying to sound so grizzled.
Let 'em have their fun. Not only is Football a sport, its a game. It is predominately about entertainment. The precident for this has been set. The Icky Shuffle, the "Who Dey" thing the Bengals did, hell, the NFL network's joking NFL Big Man Dance Challenge. Let the guys have some fun, it gets the fans into it, and its not like it hurts anybody.
To say it hurts the integrity of the game, and is unprofessional seems silly to me. We often lose sight that these are people being paid to entertain us. They aren't about to show a pie chart in a board room discussing losses, they're throwing a leather ball to other people, trying to get it to the end of a field. There's room for silliness.
Oh, and CJ's Marriage Proposal probably tops my list as far as the best, silly, contrived celebration to date. Yeah, he's arrogant. Yeah, its a side-show. But the guy is a lot of fun, and I'd love to have him on our team.
