What are your favorite Let's Plays?

I've been watching a lot of Let's Plays lately. I'd like to share the ones I've enjoyed and hear about any you really like.

My favorite so far is Spoony's Swat 4 playthrough. He really made me want to play this game and his rages at his squad mates are hilarious.

Another good one is Jurassic Park: Trespasser by Research Indicates. This game is buggy as hell and this guy knows just way too much about it.
