With regard to movies...Training Day will always be a favourite. The Will Ferrell ones will always get ya laughing too, Old School, Anchorman etc.
I like to read but sometimes find it hard to fit it in, reading Donncha O' Callaghans autobiography at the moment. I like the Pete McCarthy books, they're a good laugh.
For tv shows, Entourage was addictive from seasons 1-5, it just started to go down hill after that. The Office (UK) will always be on top of my list, some of that humour never get's old, you either get it or you don't! Republic of Telly and the Savage Eye are good for a laugh on a Monday night.
