A fan of the site made a parody of "Cooking By The Book" from Lazy Town. It is green and fuchsia lumps o' fun!
The original video it's based on can be seen here (also a Cake Wrecks post), although it doesn't explain the appearance of the dreadlocked rapper, who is based on Li'l Jon as seen in this remix (caution: Li'l Jon uses dirty words and screams like a scary crazy person!)
