In conjunction with the DVD release of Mystery Team, Derek Comedy has put out another sketch. The Chapel Hill reference alone has to make this one of their greatest sketches. If you haven't heard of them before I would suggest you start with Bro Rape: A Newsline Investigative Report, Jazz Man, and Blowjob Girl.
Another thing worth mentioning is Childish Gambino. That's the name under which Donald Glover (of Derek Comedy and NBC's Community) raps. He's released two mixtapes so far and they are fantastic. I mean he's rapping over Animal Collective for Christ's sake.The free mixtapes are available here.
