This is, I believe, a play on an ESPN announcer who inexplicably started rambling on about Britney Spears during an Alabama game.
I am not sure what game. I am not even sure if it was an ESPN announcer, but I do remember it happening this past year.
The game, whoever Alabama was playing, was nearing the end, I think it may have been Georgia. All of a sudden, this joker starts talking about Britney Spears, quite odd.
