If you think that show is stupid just based on the commercials, give it a chance, i thought the same thing until i watched it.
Anyways, after running out of fresh episode i hit up Youtube. Turns out the guys from Workaholics have a rap group, called "The Wizards".
It is an indescribably sublime mix of Wizards and Gangster rap. Check it out.
(im not sure if im allowed to link a url or not, so heres a list of their music videos on youtube)
-Straight outta Mordor
-Wizards Never Die
