Are You Being Served? (1972)

This comedy series, which follows the exploits of employees at London's fictional "Grace Brothers" department store, is full of sexual innuendo, slapstick, visual gags, and double entendres. Much of the show's humor parodies Britain's class system, and many of the show's characters are based on stereotypes of the period, including the effeminate Mr. Humphries and the rich, but stingy, store owner.
