Two callow shop clerks escape their lives of provincial drudgery for one day in glitzy, sinful old Vienna, where they hope, as one of them puts it, “to acquire a past before it’s too late.” It’s two hours of slapstick shenanigans, mistaken identities, misdirected orders, malapropisms, double entendres, and romantic complications. The play’s title is a euphemism often used by the British press to describe the actions of a celebrity who has drunk, or is about to drink, a considerable amount of alcohol.
