Can some one make sense of this?

I'll add more if I find any.

This what are they saying? Mistakes in American Pie film.

Continuity: The balls on the pool table when Finch is talking to Stifler's mom.

There are a lot of continuity errors in lots of movies, because they don't film it in one go

Yeah I know. What are they saying was the mistake I posted?

Dunno, because I was too much concentrating on the movie to notice anything about the pool balls
