PORTAL is currently the best video game ever made. If your PC can run it, go get and play it, and fall in love with the passive/aggressive AI, GLaDOS. (Just watch the trailer, you'll get a taste of the nihilistic humor that fills the game.)

If you suck at video games, you can at least read the lyrics to the fabulous ending song by Jonathan Coulton here.

Seriously, where else are you going to meet a robotic machine-gun turret with such good manners?

"Come over here, please," Blamblamblamblamblam! "Thank you."
