Man About the House was a British sitcom starring Richard O'Sullivan, Paula Wilcox and Sally Thomsett that was broadcast for six series on ITV from 1973 to 1976.

It was created and written by Johnnie Mortimer and Brian Cooke. The series was considered daring at the time due to its subject matter of a man sharing a flat with two single girls. It was made by Thames Television, and two spin-offs were later made: George and Mildred and Robin's Nest.

In 2004, it came 69th in Britain's Best Sitcom. The series was remade in the United States as Three's Company in 1977. A film version of Man About the House was released in 1974.

Young flatmates Chrissy and Jo find a stranger called Robin asleep in their bath after a party. He moves in permanently on a platonic basis, although they have to tell the landlord that Robin is gay in order to get permission for him to move in.

Robin is a student chef who spends much of the time trying to seduce Chrissy and flirting with Jo. Although the women have no romantic interest and spurn his mild advances, they quickly adapt to his presence in the flat.

The landlord, in truth a sub-letting landlord placed by the council, is George Roper, a bumbling, accident-prone and gullible man under the thumb of his domineering and sexually-frustrated wife Mildred, whose way of making up for her husband's inadequacy as landlord and lover is to make suggestive remarks to Robin and frequently side with her tenants against George.

That said, for all their battles, the Ropers are a devoted couple. After the first series, Robin's friend Larry, a lovable rogue, moves into the loft apartment and is a frequent source of trouble. Another occasional cast member is dodgy builder and schemer Jerry.
