Ooh, You Are Awful (1972)

Funnyman Dick Emery stars in this comedy caper about a pair of conmen, Charlie and Reggie, who manage to swindle two rich Italians out of £500 000. Reggie stashes the cash in his Swiss Bank account, but as they are fleeing, Charlie is arrested. While Charlie is in the big house, Reggie meets his end - unfortunately before confiding in Charlie the number of the Swiss bank account which holds their thieved bounty. What Reggie did do, however, was have parts of the bank account number tattooed onto the shapely rears of several of his lovers...Thus, after Charlie is released from prison, he must begin a wild scavenger hunt to find - and strip naked - the women on whose bottoms the treasured account number is emblazoned.
