In reference to a recent question regarding breakfast drinks, may I suggest a Prairie Oyster? The mix of egg yolk and vinegar to fine cognac qualifies as senseless lack of utility, and also as Anglophilia, thumbing one's nose at fine French cognac tradition. Some may argue that the Prairie Oyster is strictly a hangover cure, but if one is not hungover every breakfast in Hawaii, well, they don't really deserve to be there do they?
Prairie Oyster (from David Embury's Fine Art of Mixing Drinks)
1 oz Cognac
1 tbsp Vinegar
1 tbsp Worcestershire
1 tsp Catsup
1 tsp Angostura Bitters
Drop the yolk of an egg into the mixture, add a small dash of cayenne. Swallow, without breaking the yolk of the egg.
