Saying that, on my way out, I noticed you could fill in a form to donate your body parts for the sake of art and science. Nope, I wasn't even remotely tempted... I wouldn't be happy with some of the dodgy body poses they put you in.
Teachers, you can get in for free! Just show your teacher ID card and you're in.
