I have a good Elle Macpherson story as well.
My old boss was at a media event and Elle was there winning an an award for her underwear marketing and my boss was asked if he'd like to meet Elle, to which he said, yes. The chap took him to meet Elle but unfortunately my boss had got a bit flustered about the whole thing and was panicking about to say.
She said "I'm Elle, nice to meet you" to which his response was to clam up, go bright red before yelling "UNDERPANTS!!!" at her, to which she turned around walked off, leaving my boss to his shame
