Revealing mistake: When the "Asian Kid" is first introduced on the Dance Dance Revolution machine, the arrows are going up the left side (Player 1 side) of the screen, but he is obviously playing on player 2's side. To make matters even worse, the dance pattern on screen doesn't match the way he's dancing, yet the screen also shows that he's doing pretty well.
Continuity mistake: While Kyle is asleep in his bedroom the Triangle of Zinthar is on the dresser beside the framed photo, but in the next shot when the cut ceiling falls onto the floor the Triangle has vanished, then it reappears on the dresser where it is supposed to be. (00:07:40)Super Grover
Continuity mistake: When Randy and Stan leave the dinner table Sharon tells them about her friend Abby, and there's a table beside the front door with two drawers, but when Randy opens the front door the table now has legs and the drawers are gone, then it reverts back. (00:11:30)Super Grover
Continuity mistake: When Randy breaks into the trailer that has access to internet, the locked front door has a large "Red Cross Only" sign attached to the exterior side of the door, but when the guards unlock that door the large sign vanishes between shots. (00:18:20)Super Grover
