What... the hell?

Um, okay, I'm at school in Pascal right now, and a minute or so ago, I heard someone say "You look familiar." I didn't think he was talking to me, but he sounded like he was standing awfully close, so I turned to look. And there was some random guy who I've never seen (or at least paid any attention to) before standing less than a foot away from me and looking down at me. "You look familiar," he said again. "I think I've seen you somewhere before." And, while I'm sitting there going, "Um... uh... I don't think..." he just turned and walked off.

Double-you tee eff? o_O

(EDIT)

Actually, yeah, I realize who it was now. In retrospect, it's not too surprising who it was, really. I'd just never gotten that close of a look at him before and so didn't immediately recognize him. Now that I know who it was, I am less confused, but no less disturbed. (Hint, for those who know who I'm talking about: it was the mega-freshman.)
