The first non-official StarCraft2 video I've seen so far, set to the tune of Banana Phone:
If anyone knows where to get this skin pack, please post it in the comments 
There are some other worthwhile videos at the Machinima YouTube Channel
From the youtube description:
"Meet the Spy, one of nine playable character classes in Team Fortress 2. He is deadly—handsome, that is. But mostly deadly. He is a puzzle, wrapped in an enigma, shrouded in riddles, lovingly sprinkled with intrigue, express mailed to Mystery, Alaska, and LOOK OUT BEHIND YOU! but it is too late. You’re dead. For he is the Spy—globetrotting rogue, lady killer (metaphorically) and mankiller (for real).
First video of Meet the Spy on YouTube. Enjoy."
(The music is less than desirable in some of these, but they’re more about the eye candy than the audio supplement)
First, there was the (somewhat…but not really) revolutionary surf_fruits
Then, came the slightly more polished surf_vegetables
And finally, after much anticipation and speculation, the latest release from Velocity Studio, surf_animals 
All of these lovely maps can be played on [F10]Surf-n-Turf, more info can be found on the F10 community portal
There’s been a lot of talk about Eve-Online recently, thanks to lots of recent publicity from in-game events but also after the announcement of Apocrypha, the latest free expansion which is coming soon™ (allegedly in March). Aside from the recent disbanding of the BoB alliance thanks to Goonswarm, a recent devblog has given a bit of information on the introduction of the highly anticipated "Tech 3" ships. If you’re interested, I won’t bore you with the details (the actual devblog can be found here), but I will show off a nice concept art pic of the new Minmatar Tech 3 Strategic Cruiser:

This is a clip of the PC fighting game M.U.G.E.N. I’ve never played it but I’ve heard it’s pretty epic, and this clip alone makes it look supreme for all things random
In case anyone cares, the song played in the intro is Godspeed by the band Anberlin
I think I found this on Digg a while ago, one of my favorite random internet videos.
Sit back, relax, and feel the zen….
Random clip of a classic Nickelodeon show, showing (a likely very high) Marc Summers during his prime on Nickelodeon. This brings back memories of all the great shows that used to be on TV back in the early 1990′s, I hope everyone else enjoys it too 
Now this is just epic
Is apparently not dead like everyone thought. I remember seeing this way back in 2003 or 2004 when Half-Life 2 first came out, and thought it looked cool but also kind of assumed it was never coming out. Much to the surprise of everyone, a trailer was released yesterday and it looks pretty damn cool:
