Sometimes, objects thrown like a frisbee can behave weirdly. I once threw a paper ninja star, and it curved right, then left. I believe that's known as the Magnus Effect. @Chish: That effect commonly happens...and also depends on environment. It's different when you're in a classroom with minimal air flow vs. a hallway or alleyway with a draft.

That said, I think Brisk got it right. I'm no physics expert (did the AP class for it, hated it) but the link to the article is here. If you want to jump straight to the physics portion of it instead of doing 1 or 2 seconds of scrolling, here's the sectionfor it.
