Isn’t “fat ugly dude wins smoking hot woman because he is smart and funny and kind to animals” the plot of Shrek, though? Sure, he’s not kind to donkey at first, but ultimately he is. Princess Fiona is smoking hot in the Shrek world, and possibly a smoking hot ogre - who knows with ogres?

But yeah, I can’t think of an inverse cultural example. I wonder if it’s actually pretty common in real life, though.
