If you've played the original, you need to watch this series. At least watch the first three or four, and if you don't at least chuckle, you're a humorless bastard.

I had to stop for now at number 8 because I was laughing so hard my jaw ached. I've actually said some of this stuff out loud while playing!
I should probably add that some of them are NSFW due to salty language, but you shouldn't watch them at work anyway because you'll be laughing so hard you'll probably cause a sharp decline in productivity.
