A karting and paintball day out, quick wash and change followed by a bostin' night of poker with the lads with some cigars and whiskey, and a stripper or two of course.
Simple, effective, enjoyable. Nothing saddens me more than seeing a group of lads out on a stag do and the 'stag' being stupidly drunk because his mates keep giving him cocktails. I just don't see the point in that. I would want to enjoy and remember my stag do.
