most fun charity thing i was at was a load of fellas being waxed, few pints later we were bidding to get to wax various "hairy" bodyparts, lads kinda just rolled with it.... followed by a raffle for alcohol and other prizes, followed by a few raffle prize winners starting an impromtue auction selling their raffle prizes in aid of charity, made about 600euro that night if i remember right, whole pub put a few euro in the pot
