Trixie losing to Pearl was always a big surprise to me. Pearl's performance had been poor up to that point and I don't remember her doing anything to redeem herself in the lip sync at all. Trixie meanwhile was at least quite a memorable contestant by then and had had some funny moments (remembering this is of course pre- her coming back, All-Stars and her post show fame)
Can't find a video of the lip sync unfortunately. Would love to see it again and make sure I'm not chatting shite.
