Something that makes no sense

Um.....if that was the case, one of 'em'd have to be female.

You didn't know? Luigi is female!

hey don't judge him if he does identify as female

You don't have to be female to sport a spankin' dress and also look fabulous in one.

I'm late but...twins aren't always identical. I have twin cousins who are unalike in both looks and personality.

Also Mario's older because twins never come out at the same exact second.

I know that. There's another kind of twins, fraternal, and genetically, they're nontwin siblings.
