Can you tell her that 1977 called, and wants its movie reference back?
Just kidding, I suppose that's not e-hell approved. Honestly, I'd just roll my eyes and keep quiet when she does it, she's only making herself look silly.
Nerd confession, I do occasionally try to pull the "jedi mind trick" on DH now and then. But, that's because I know he is a big SW fan and has seen all of the movies at least 10 times. I wouldn't do it to a waitress or a stranger in a store, though.
Bit of a threadjack, but it's a pet peeve of mine when someone "discovers" a band, movie, or other pop culture thing that's been around for years, and can't quit talking about it. I had a cousin who decided a couple years ago that the Beach Boys were the best band ever. He'd tell you, "You have to hear this song!" and it would be like, 'Little Deuce Coupe', or something. I'm thinking, um, yeah, it was great like, 30 years ago..
