1983 Oregon State vs. Oregon football game

The 1983 Oregon State vs. Oregon football game was a college football game played on November 19, 1983, at Autzen Stadium in Eugene, Oregon, the 87th playing of the annual Oregon–Oregon State football rivalry game, then known as the Civil War. The game ended in a scoreless tie, and since overtime was added to NCAA Division I games in 1996, this is likely to be the last such game. However, there have been two more scoreless ties in regulation since then, in 2005 and 2014.

Due to the very poor standard of play, including eleven turnovers and four missed field goals, as well as the miserable weather conditions in which it was played, the game is often referred to as the Toilet Bowl.
