My only pants story:
Back when I was in high school, the community theater group did a rendition of A Christmas Carol. (I had a bit part.) The guy who played Scrooge was an older gent who, shall we say, was no gentleman. Pretty much everyone hated him.
The first night of performance, after all the ghosts had visited and he's getting dressed as he's calling out to the goose boy, he put his trousers on backwards. Not missing a beat, he fastened them in the back and finished the play.
He never lived that down. I ran into his wife several years later and she said she was still razzing him about that.
So I guess there's one more option for pants, eh?
