British Television programme about cars. Used to be not so good and lost a lot of viewers to other programmes on other channels, but recently had a huge revamp and now has a great blend of real stuff about cars, with a good amount of humour as well.
Presented by Jeremy Clarkson, James May and Richard Hammond, who between them cover the wide range of topics. And of course, there's "The Stig", a racing driver whose name isn't officially revealed, who takes various cars round a test circuit (while listening to cheesy 80's power-pop tunes) to see which one gets the best time.
In short, if you have any interest at all in cars, or just want a good laugh at Jeremy Clarkson at his best, this is well worth a watch. Sunday evenings, BBC2 at the moment.
