I don't know... I kind of like Khorne's.
If only for the fact that the same thing happened to me in grade seven, except I got pants-ed, instead of them falling down.
Which actually reminds me of another story. I got suspended from school in grade seven, for undisclosed reasons. (I was a moron then.) Anyway, they had brought my mom and sister into the school and had a chat with the principal while I waited. When they came out, they told me to get my books from my locker to take home, and they watched me get them. Back then, I was only about 5'1", so I had to jump to get something at the very back of the top shelf of the locker. Of course, I was sullen, and they had those really pissed-off looks. So I jumped to grab my books, and for some reason... *fwoop!* Down go my pants. I was almost too ashamed to laugh, and I looked behind to see them fighting their hearts out not to smile. Ah, comic relief. Where would we be?
