Funny Money

On his birthday, middle-aged Henry Perkins is going home to Fulham on the underground, looking forward to his birthday dinner, for which he and his wife Jean have invited their old friends, Vic and Betty Johnson. Nothing out of the ordinary has happened so far, but on the tube train he by mistake picks up a wrong briefcase without noticing it. He gets off at Fulham Broadway, wants to get out his gloves and scarf and realises that he is actually carrying someone else's briefcase. In it, he finds £735,000 in used £50 notes. He goes to a pub and counts the money several times in one of the booths of the gents. "Bent copper" Davenport - in plain clothes - watches the excited man and believes he has come to the pub to solicit men.

Foreseeably, unforeseeable events intervene. While he is still explaining to his reluctant wife that they have to leave in a hurry, Davenport - whom Henry does not recognise from the pub - arrives and wants to have a talk with him. Of course Henry thinks this is about the money, and a whole series of (deliberately) mistaken identities ensues, which also includes Vic and Betty, who are introduced to Davenport as relatives of the Perkins' on their way home to Australia. Bill, the taxi driver Henry has called to drive his wife and himself to Heathrow, adds to the confusion.
