We made them down a pint then sat them on an office chair with pictures of the ac choices round it and spun them blindfolded. On stopping they would be pointing at an ac. We handed them an egg and they had to smash it on their head, if it was raw they didn't get the ac choice and had to down another pint and go through through the whole process again, if it was hard boiled they got the ac. Great way to tease, humiliate and induce vomit.
