DERRICK is a comedy group in New York City. The members are Dominic Dierkes, Dan Eckman, Donald Glover, and DC Pierson. They chose the name DERRICK because all of their names start with 'D' and they thought it would be cool to have another 'D' name. Anyway, they're pretty much YouTube Celebrities - they're the 3rd most popular comedy group on YouTube. They also perform quite frequently at the Upright Citizens Brigade Theater.
Here are some of their best videos. Probably nsfw, there's no nudity but a lot of swearing.
