For once, a protagonist who doesn't smoke! I swear, they love their cigarettes in Great Britain, and it seemed in every sex comedy, someone is lighting up.
One of the movies from the British-made "Adventures" series, this one is actually a good one. A likeable Lothario plumber named Sid is having trouble paying the bookies and must get 1000 pounds paid to them or "else". In between plumbing jobs, he works for a small-time crime boss who gives him "jobs" to do, and they all go wrong for him. As with all movies in this series, people go naked, but here, there aren't any sex scenes for once, but there are some funny scenes created from the situations the plumber gets into.
Stephen Lewis, who played Inspector Blakey from "On The Buses", has a small role as Sid's boss, the aptly named B.A. Crapper. Yes, this is a very British film, with some people's accents being very difficult to decipher, but it's still worth seeing, although it's probably unavailable in the U.S. If you live in a British Commonwealth country, you'll find it.
