Feeling a little nostalgic sort of sadness now that I've finished watching Jeeves and Wooster (the ones that can be watched on my iPod anyway).
Anything from Fry and Laurie does that to me and makes me wish I live in the 90s. A Bit of Fry and Laurie, Jeeves and Wooster, Peter's Friends.

And I think I haven't really said it here, but Douglas Adams is awesome.
