Some of the old British sitcoms are very tired but there are a number of classics - Fawlty Towers, Not the Nine O Clock News, Blackadder, etc.
Here in the UK we cannot understand why Benny Hill's dated sexism is given the time of day, but there are many contemporary jewels.
One of the best is Still Game on Netflix, about a bunch of old Scottish guys living in a run-down area of Glasgow. Sometimes the language is a bit fruity but the humour is spot-on. If you make it past the first two or three episodes I guarantee you'll be completely hooked.
