Personally, I'd prefer the chick flicks thing, but since it is a Super Bowl pre-game party, you'll stir up much more interest if it's game themed.
Will there be a tv for watching the game?
Can you have some sort of quick knit project that could be done in game colors (even a football, or game colored hat,...I don't know, I'm not that sports minded. :))
What about door prizes to be given out at every touchdown?
I'm sure others will come up with good ideas, but just be sure you keep the hot wings separate from the yarn!!!!
