Just randomly came up with an opener while reading and thought I'd throw it out here. It's an indirect and diverse opener. It can go at least 6 ways depending on the girl and how you want to seduce her.
'When I say Ceasar what is the first thing that comes to your head? (The roman general, the haircut or the salad)'
You don't have to say the last part but she will most likely say one of those three (unless there's another caesar I am unaware of). Whatever she replies you can come back with either a neg or a compliment. If she says general, you can say something like 'Woah, come back to the 21st century grandma' (neg and validation) or 'Nice, a cultured one, you get 10 brownie points' (again validation, but using a compliment). If she says the hairstyle you could say 'Oh man are all girls obsessed with fashion or is it just the ones I meet?' (you're displaying preselection and a neg if you say it right) or 'Nice a girl with fashion, I like that' (again validation). If she answers salad something like 'It doesn't hurt to eat a burger once in a while, you look a little skinny, put some meat on those bones!' (neg) or 'Right on, a girl who watches what she eats' (compliment).
I thought it was pretty cool cause you can get her validating herself ASAP while remaining indirect. You basically get to a3 within 10 seconds. I just came up with it 3 minutes ago so I obviously haven't used it. It's sounds super technical but shouldn't be too hard to pull off. Anyway just thought I'd throw it on here for you guys to try out if you'd like!
