Dunno about no Beer Bongs n all that, but here in the UK, it is customary for all visitors to these fine shores to have a YARD-OF-ALE in the first real pub they visit. Basically (in case you don't have these in the US) it is a beer glass a yard long. Full. With the object being to down it in the fastest time possible.
Those of you who have visited the UK previously and do not have your Certificate of Yardsmanship will have trouble passing through customs next time you visit.
