Maybe guys like girls at first because they're pretty, but I'm sure Mickey fell in love with you for a lot more than just the way you look, and that's what makes you pretty to him!

... U-um, not that you're not pretty to anyone else, because I always thought you were were pretty in... um, cartoons, but-- what I mean is, your heart's still Minnie Mouse, isn't it? So no matter what you look like, he'll always think you're beautiful!
