The You Game!

[Bradandez]

< isn't getting <'s copy of Smash Bros. until tomorrow.

[Master]

Speaking of Smash, here's the Finale of Brawl in the Family, < will watch it in due time also:

[GOT4N]

< got 3DS Smash Bros

< Finds that amusing.

< Also got the 3DS version this morning.

[Bradandez]

Just rub it in <'s face, why don't ya!!!

[Imco]

Hey Brad, you're not the only one who doesn't have it! < doesn't have it, because < doesn't like the stupid game

[Reese Riverson]

< Likes the idea of being able to play the game on the go.

< Also wonders when Mastré LeMashed will be getting a 3DS.

[Earth Gwee]

< is waiting for dinner and < is super hungry. <'s stomach won't shut up.

[Bradandez]

Hey Brad, you're not the only one who doesn't have it! < doesn't have it, because < doesn't like the stupid game

< Also wonders when Mastré LeMashed will be getting a 3DS.

Let's start a kickstarter to get him a 3DS.

< is eating waffles and filling out job applications.

< Absolutely wants to watch Ed, Edd, and Eddy after ^ posted that picture of Kevin with the Dork sign.

< Also finds the kickstarter idea to be a good idea, it would be for a good cause!

[THEdragon]

< Changed the desktop background of <'s parents computer to an image of the Musician tiling repeatedly. They have yet to find out.

[Fifo]

< wonders how to decode the Rayman 2 soundtrack. < wants something to do. <’s bored.

[Shrooblord]

< wonders why ^ wants to do that. They're all simply audio files in one of the folders of either the install directory or the CD itself. < has near to no hacking skill whatsoever and easily found them.

< finally found the solution:
