The Immaculate Reception was also a blown call. According to John Clayton of ESPN, that play should have been called back. It seems that in the 70's two players from the same team could not touch the ball. The pass deflected off of 1 Steeler player and was then caught by Franco Harris, which would have been a rules violation. However, the play was allowed to stand and the Oakland Raiders were screwed out of a game. The Steelers made the playoffs.

It happens when the Regulars are at work too.
