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 compelling captures from the world of insane speed-runs, chance kills, competitive moments, and hilarious happenings from the past and present.

Be sure to check out last week's edition for more crazy digital stunts and creative stupidity. And now, on with the show.

Video of the Week: Crysis vs. Mechachicken ( link to this video)
If you haven't fired up the Sandbox 2 editor included with the Crysis demo, what are you waiting for? FinalFrog's montage of nuke-on-chicken devastation can be replicated by adding a few items to the stock demo map and playing within the editor (control-G). You'll find the nuclear-equipped tanks within the Archetype Entity/Vehicles directory, and the hand-held TAC launcher in the standard Entity/weapons folder. Giant chickens sold separately.

Rocket Poltergeist ( link to this video)
This week's choicest Halo 3 clip comes from sssViPeRsss, who bore witness to a real-life rocket possession. Is it physics, or spirits from beyond? I know what Dan Aykroyd would say, but watch and judge for yourselves.

Grenade: The Reckoning ( link to this video)
In a similar act of ghostly intervention, CptSchrute's errant grenade toss crosses streams with fate. The resultant reversal of particle flow creates an alternate reality, where some other guy gets his face exploded.

Inner Demons ( link to this video)
This Skate video comes from KTS over at the awesome Goonskate website. Watch in horror as a security guard, clearly some kind of demonic servant of evil, ravages our poor skater. Dude, not sweet.

Classic Trailer of the Week: Diablo ( link to this video)
Sure, this next clip wasn't exactly generated by some guy in his basement, but it is technically a replay. Hopefully I'm not the only one who digs on old game trailers. This one is the perfect anti-Peggle, a dialogue-less gem from Blizzard's early days, which debuted on the WarCraft II CD.
