I was going to save this to myself when I would be going to ask a girl out for prom, but hey, magicians are all friends so...here's my suggestion: You buy blank decks, write letters on them. And then you go up to the girl, tell her to pick a card (with normal cards), put her card back into the deck, do a deck switch to the blank deck with letters and spell out, "Screw the trick, you're more magic, will you go to prom with me?"
