The Starcraft one is from a custom map Blizzard made like four years ago now...a rather retarded Capture the Flag type thing (I tried playing it with friends, it is horridly chaotic)...but the song made it all worthwhile. Toss this one in with "jokes that everybody who cares should have seen a long time ago" though...
Dear god, this one is friggin hilarious. I can't stop laughing at it. I mean, the guy is genuinely upset that the Pop Tart wasn't hot. And the song choice is just... perfect. Winner.
