For some weird reason, this thread reminds me of the time in the Australian Revival of Rocky Horror, when Frank 'n' Furter (Craig Mchlachlan) had a "wardrobe malfunction". He fell over while performing sweet transvestite, caught his stocking on a piece of the set, then off came his costume alltogether. Let me tell you, it wasn't pretty...more than just a bare ass and breasts...
(Sorry to get off topic)
A little known fact is that in the original screenplay, Pan's Labyrinth was Pan's FLAByrinth. Hmmmmmmm...glad they changed it.
