The Bathroom Thing - now with stuff written on it!

I've been mucking about with annotations in YouTube...so 'The Bathroom Thing' now has both a title *and* a credit to the RVT at the end for letting me use their toilets to shoot my guerilla poetry video. It'd be nice to go back there sometime and get it filmed professionally, with someone else holding the camera etc - though the RVT toilets *are* kinda cramped. What about it - do readers know of any toilets roomy enough to film in?
