Factual error: Right after Lance gets hurt and Mox replaces him Mox's first play is a 40 yard pass for a first down after which everyone starts yelling he needs to stop the clock and the camera shows the clock moving. The problem is that in high school football the clock stops on first downs while they reset the chains so the clock should have stopped running until the first down markers were moved and the ref set the ball.
Continuity mistake: When Billy Bob is holding a camera when tweeter is about to hit the guy from the class of 1980, if you look towards the right, you see that Coke and Sprite cans are on opposite sides of the table. After the guy from the class of 1980 gets hit and the camera goes back to Billy Bob, you see that both of the cans are together and are on the other side of the table.
Continuity mistake: In the beginning when Mox comes downstairs and is talking to his father at the breakfast table his Father has his tie over his shoulder, then the little brother comes in the room and knocks the tie off his shoulder, then the camera goes back and forth and the tie is on shoulder, then off the shoulder.
