The 1972 Alabama-Auburn Game

17 - 16 Auburn

Down 16–3 late in the game, Auburn blocked two punts and returned both for touchdowns, leading to an improbable 17–16 Auburn win and the coining of a new phrase among Auburn fans, “Punt Bama Punt!” In August 2010, ESPN.com ranked this game the 8th most painful outcome in college football history. Alabama would go on to win the next 9 games in a row (1973-1981), known to Auburn fans as the “Reign of Terror”.
