Recalling an advert from my youth in Sydney, Australia:

With a couple of couples about to go away for the weekend, the gents are piling-up the back of a ute/coupé utility with tinnies (cans of Foster's Lager, maybe) when one of them considerately says something like: "Suppose we better add a bottle of sherry for the ladies, mate" - upon which the whole thing collapses, of course, and the other one says "Looks like we overdone it with the sherry, mate".

(Better, maybe, when I've said it at a pub, with a broad accent, and everyone having had a few.)
