Oh my. It is very possible that it was me as that sounds like something I would do. I cannot for the life of me remember doing anything like that, though I will admit to blocking out most memories of speech class due to the teacher alone.

Do you recall if you were in the class with a guy who decided to do a speech on Spam? And then proceeded to bring a can of said stuff into class? If so, then we might have hit the nail on the head. Except that I still want to dig out my yearbooks (if I can find them) and go looking for you.
