For those of you that follow videogames, specifically the Mass Effect series, this will be a hoot:
Someone did a neat job of photoshopping the cast of Community as characters from Mass Effect. I believe the original source is obiruskenobi.wordpress.com if the credit at the bottom of the pictures is accurate, although it says obiruskenobi.tumblr.com for me when I follow the link.
If you happen to see the artist's take on the NBC logo, I guarantee you will be highly amused (if you have played the games). It is absolutely brilliant.
