Character mistake: Right after Hyde comes into the kitchen to get whipped cream for the stripper wife, Kitty Forman says "Kurt" instead of Red to Kurtwood Smith.

Character mistake: As the little boys are trying to get a peek at Donna's breasts, you see more and more of them. The first two times, you can't see them. The final time, you can see a kid or two far left. They're having trouble standing still. When it cuts to a wider shot, the kids come from behind the wall to see Donna. Chances are, since the aspect ratio was intended for 4:3 TVs, they didn't intend for the kids to be visible.
