Leave work and go home to your Xbox and download Blow at once.
You'll be a nicer, happier person for it.
And if that isn't enough reason to do it, then let me assure you that there is a whole lot of game packed into this little $5 Community Games download. The sample you see in the free trial runs out before you even scratch the surface of the game.
Seriously, it's better than many of the XBLA games that cost 2-3x as much. Get it.
