While people are recommending stuff, yes watch J & W, and Fry and Laurie's comedy shows, both are brilliant, but do not miss Blackadder. (Well, skip season 1 until and if you become a hard core fan as even us UK fans find that one a bit hard going.) Worth watching S2,3,4 as not only are these two in it, but you're going to see Rowan Atkinson (Mr Bean and Jonny English) at his arguably best, and many other brilliant UK comic actors. (Actually, IIRC, S3 and S4 are the ones that bring him to the fore. In fact Im not sure he was in S2 at all. Cant remember.... Im old!!!!) Blackadder S4 is truly an awesome comedy series. Its worth watching fully and properly just to see how they ended it. Do not skip the series for the ending, you will ruin its power. Let it build up, then tear you to pieces.
Personally speaking is cracked me up when House first started and the US treated him like a proper normal actor, while we in the UK knew his comic roles. But, brilliant for Hugh as he could almost start a new career as a serious proper actor with out the "baggage" of comedy. You guys, if you haven't already, now have the sheer delight of checking out his back catalogue.
I was going to add some YouTube links, but as I was going through the site looking for some gems, I realised I would end up adding so many links I would look like an automated spammer. So, you know, hit YouTube, search, and loss a few (un)productive hours laughing :)
Oh and thank you America for giving him a chance to be a proper actor. I don't think it would have happened in the UK. Type-casting and all that.
