So this guy walks into a booksigning, and...

I'm going to take up from Michelle Gagnon's terrific post on planning a book signing and pose a question: what is the funniest thing that has ever happened to you at a book signing? Either as the guest of honor or as an attendee? John Gilstrap tells HILARIOUS stories about doing a booksigning at Costco,involving the bay doors and a de facto wind tunnel. Sandra Brown also tells a great story about the first signing she ever did. What's yours?

I don't really have one. Well, yes I do. I did a signing at a local store and was all set up by the entranceway, showered, shaved and tap-dancing, and actually had people who weren't related to me or in my circle of friends buying books. A guy --- a big guy --- walks through the door, sees me sitting there signing a book for a very nice lady, and rudely interrupts, asking "Where's the music department?" I immediately responded, "Second floor. Turn right at the top of the escalator and go all the way back." Of course, that was where the restrooms were located. For all I know, he's still looking.

Your turn.
