This has been bugging me for awhile. IMDB has a wrong trivia fact listed for the actress who played the love interest, Ramona in the Season 9 ep Bully for Arnold. IMDB has the wrong actress credited (Beverly Brown) for a teenager role. The young girl looks to be 16-24 years old. You can tell that she's young complete with acne and braces and not some 60+ year old.

Could there be another Beverly Brown they got her mixed up with? That is weird. No way is that girl in her sixties.

Could it be Beverly Johnson?
