Jimmy Carr is one of the most brilliant comedians I've ever seen. He's known by his crude language and offensive jokes, but even those are very smart - he likes to work with puns a lot and one-liners that usually don't let you go "oh for f*cks sake" because after he finishes one, gets the laugh he goes onto his next one and you'll be laughing out loud the entire show.
The heckles are always an amusement, even though he recycles a lot of his comebacks. His show always gets the same format which is fantastic for the viewers, because trying to hard is something we can all see and Jimmy Carr is just a natural gifted comedian. I hope people get notice of him and his stand ups. He takes life lightly in subjects that people are way too sensitive about. Sure pedophilia is a crime and he speaks a lot about it, but it's not like he's saying people to do it - he just wants them to laugh at an hypothetical situation.
If you're going to watch this hold your horses, say "f*ck it" and enjoy. You'll absolutely love it.
