1. "Keep your paws off my underwear." Hee hee!
2. The idolizing way Roxie is staring at Velma in the beginning when she's fantasizing about being the star herself. Yeah, we all know she wants to be up there in Velma's place, but wanting to be someone that badly and wanting to do them get kind of mixed up sometimes.
3. At the end when they wind up "together", at least in a business sense, they've got their arms all over each other and look buoyantly happy. And how's this: "You can even marry Harry, but mess around with Ike", and if you look at their reactions to the "mess around with Ike" bit, they've just turned toward each other and smirked heavily. Hee!
4. The other random lesbionic things about the movie: Mama acting like she's about to jump Roxie AND Velma and probably everyone else, which doesn't surprise me considering it's a prison movie. And the fact that the whole thing is full of jiggling breasts and jutting hips but is so anti-man that nobody who's XY could comfortably enjoy it all :P I mean, all the men who got whacked "deserved it" in the movie. I don't believe in that kind of black-and-white logic in real life.
Anyway, it's also HAWT so who cares about reasons, right? ~_^ Feel free to add your own. I'm curious! ^_^
