Henry Fairlane is the typical bored officer worker, he's irritated by the size of his office and the adornments, worse though, he's sexually frustrated, that is until his colleague Roger Gresham suggests a party, a party where keys are involved.
A somewhat more risque comedy from Galton and Simpson, and definitely one of the funnier ones from this series of seven comedies.
It's almost like a French farce, wild goings on, the frustrated husband, the beautiful wife, it's very amusing.
By this point we'd already had the swinging sixties, and things had apparently cooled down a little by this point, but of course you never know what goes in behind closed doors, and there's a lot going on in this flat, well not for poor Henry that is.
Briers is very funny as the frustrated Fairlane, what a good comedy actor he was, and what a change from The Good Life and Ever Decreasing Circles.
8/10.
