I had padding for a bra while I was in a school play, because the costume swallowed my boobs.

I forgot all about the padding, because I never used it outside that play. I left it in the green room by mistake.

Not that scandalous, I know... but to this day I wonder what the janitor thought when he found it. Did he know what it was? Did it wind up in the lost and found? Maybe he took it home and paraded around wearing it.
