This awesome video by Scott Gairdner is a great sendup of bad reality TV.  Funny from begining to end, and with great production values, it is a rare piece of sweet, sweet corn in the foul, murky shit of internet video.

This is the slowest playthrough of SMB Level 1 that I have ever watched, and is a record that does not need to be broken.

This mod for Unreal Tournament 3 looks fantastic and makes me want to get a copy of the game.  The 2d gameplay is inspired.  With a little poish, this could be one of the most interesting game mods I have ever seen.

There have been many videos online of people performing the super mario brothers theme song in interesting ways, but this has to be the most original I have seen so far.

This article and accompanying video are awesome. From the article: "But, we can kind of think of the multi-playthrough Kaizo Mario World video as a silly, sci-fi style demonstration of the Quantum Suicide experiment. At each moment of the playthrough there’s a lot of different things Mario could have done, and almost all of them lead to horrible death. The anthropic principle, in the form of the emulator’s save/restore feature, postselects for the possibilities where Mario actually survives and ensures that although a lot of possible paths have to get discarded, the camera remains fixed on the one path where after one minute and fifty-six seconds some observer still exists."

This is one of many videos on youTube of Syobon, the Evil Super Mario Brothers clone, which appears to have been built by a Japanese 2chan-er. This game is brilliant in its abuse of the built in gaming instincts many people have with regards to the classic super Mario Brothers game.

"Twas The Dark Knight Before Christmas" is a interesting take on the classic Christmas poem created by youtube's ItsJustSomeRandomGuy.
