Party number 4 took place upstairs at Clockwork just off Pentonville Road.
Costume highlights included a gigantic polar bear, Borat, Venger, Blade, Spiderman (Fathers 4 Justice), Interview with a (pair of) Vampires, The Joker, Noddy Holder, The Spanish Inquisition, Cheetara and Medusa.
The dude dressed as a polar bear romped home for the best costume prize. He will join a select band of champions and have his name crudely engraved on the plastic skull trophy.
