The Irish legend says that when ye get up to te' pearly gates and St Peter is standin' there to judge yer life, one t'ing he does is roll out a barrel wi' yer name on it.
In that barrel is every drop of the creature that ye ever wasted. So St Peter un-bungs yer barrel, and upends ye into it head-first, all the way down. And if ye drown, then te hell wi' ya!
