Corrected entry: When Wally and Dave are marching out with the protesters, Wally is waving his hands in the air like the protesters. How would he know they are raising their fist in the air? He's blind. (00:36:15)
Corrected entry: Wally says he got blind because a drunk driver hit him when he was a kid. As a kid he should have seen that he was black. So his surprise about not being white at the beginning of the movie makes no sense.
Correction: He was not surprised to be black. He was joking.
Corrected entry: Near the end, while Gene Wilder is looking through binoculars he is having a conversation with Richard Pryor's character. The flub comes from Wilder's character being deaf and needed to read the lips of whomever he is speaking to. He couldn't do this while looking through the binoculars.
Correction: It does seem like that, and happens later on, but in this particular scene, the things Gene Wilder says are perfectly possible for him to have said unprompted. It seems like he is conversing with Pryor because Pryor can hear him, and so can reply correctly.
Correction: He asked what's going on and Dave tells him "protesters." Wally already knows demonstrators raise their hand when marching, which he tries to mimic to blend in. But he's not doing it exactly as the protesters are doing it since he's only guessing.
