What would あなた say was your weirdest/ funniest case of gender confusion involving a cartoon character (thinking a character is the opposite sex)?

Mine would definitely be...ugh... Flintheart Glomgold. lol Back when I first saw DuckTales, when I was like 4 years old, I actually thought he was an old woman. :P I was sure that his beard was long hair that hung around his neck, and of course, his kilt was a skirt.

But of course, I've since learned he's a he. lol
