Other mistake: When Rocky is in the funhouse looking at himself, he appears to look relatively "normal". But it's very obvious that it's got nothing to do with the mirror, and more to do with the removal of a lot of makeup. For example, Rocky usually has almost no nose, but in the mirror he has Eric Stoltz's very well developed nose.
Rocky Dennis: Mom. Do I look like a freak to you?
Rusty Dennis: No.
Rocky Dennis: You know, your always been big on telling me when my face doesn't matter, but, it does. Doesn't it? You think that I can't even get a girl to like me unless you pay for her.
Rusty Dennis: That's not true.
Rocky Dennis: Bullshit.
Rusty Dennis: Bullshit yourself. You know lots of young guys got problems getting girls. Well, what if I was your dad and I did the same thing?
Rocky Dennis: I'd hate that too.
Rusty Dennis: First you told me he was gonna be retarded, then you told me he was gonna be blind and deaf. If I'd dug his grave every time one of you geniuses told me he was gonna die, I'd be eating fuckin' chop suey in China by now.
Rocky Dennis: Don't worry, Mr. Simms. I look weird, but otherwise I'm real normal. Everything'll be cool.
