Welcome to the Replay Couch, where we kick back and watch the best, and worst, of recorded video game history. Each week we'll be offering up a compilation of captures from the world of insane speed-runs, chance kills, competitive moments, and hilarious happenings from the past and present.

Also, be sure to check out last week's edition for more crazy digital stunts and creative stupidity.

Cake or Death?
Like old Nazi invasion footage, this somewhat low-resolution capture is no less of a conquest. Watch in awe as Portal chamber 15 falls to the blitzkrieg of npaltmp.

After that, it was back to more exciting diversions, like the fly-squashing mini-game, or Super 3D Noah's Ark. Simple 3D distractions are not for TomBobBlender, the mushroom maestro, who dazzles us with his rendition of a vintage Mega Man 2 beat.

Take A Seat
I had so many requests to post this now-classic Skate video that I had to give in. Alright, three people asked. But it's not like it gets any less funny. He lands right on it!
