Other mistake: When Hayley is chasing Steve and his friends in her car, after Steve gets on the bus, Hayley turns around a corner to follow it. When this happens, the license plate on Hayley's car has nothing written on it.
Roger: Look at us, Steve. Neck and neck. May the best man win. Steve: Well that's gonna be me, because your weird gut's about to hit the wall. Roger: Not if your boner hits it first. Steve: What? I don't have a boner. Roger: You're about to. Steve: How? What are you gonna do? Roger: I don't have to do anything. You're a teenage boy who just heard the word "boner." It's already happening. Steve: No. Not now. Not like this. Oh, God! Not like this! [Steve struggles to prevent his erection but it's heard hitting the wall.] Steve: Damn it. Roger: Yes! I won. Francine: You did, Roger. But, in a way, I feel like we all won. Roger: What? Wait, what? Francine: Because it brought us all closer together. Steve: You're right. I thought I was in a race, but really, I was in a family. Roger: Okay, I see what's happening here. Yeah. You're trying to screw me out of my victory. We all heard his dick hit the wall.
Trivia: Roger has various weird objects stored up in the attic some used as furniture for his own means. One which contains the address to Roger's spaceship, which is hidden away in storage as shown in this episode.
