I once watched a Texas A&M player sack an Oklahoma quarterback with under two minutes left in the game and he commenced into his jivin' stylin' gyratin' happy dance. One of the Oklahoma players came up and motioned to the scoreboard. A&M was trailing 63-7 at the time.
There was a funny clip of the Miami Hurricanes players dancing it up on the sideline during the game against FIU.
Only thing is, at that time they were trailing FIU (yes, FIU) 13-0, and they went on to lose the game, in arguably the worst loss in school history.
