Continuity mistake: When Doug Masters and all his friends are at the burger joint and Masters has just received a letter saying he has been denied enrolment into the US air force academy, his enemy Knotcher tries to humiliate him by announcing it over the loudspeaker. Masters then runs up to the window and threatens to assault him. Knotcher suggests that a race would be more appropriate to which they both agree. During this whole conversation, Knotcher's right arm is up, next shot it's down, then up, then down again.Gavin Jackson

Doug Masters: How can you think with that music on?
Chappy Sinclair: Aw come on, let's see what you got.
