In many episodes Al recounts the legend of how he scored 4 touchdowns in one game to lead Polk High to the city championship. However, in one episode -- the episode with Bubba Smith -- it is noted that he scored the only touchdown in that game.
In the scene that spoofs the opening of Branded, the principal breaks Al's baton over her knee. In the following scene, Al holds up one of the broken pieces; the break is mostly smooth, suggesting that the baton was partially sawed in advance to make it easier to break.
