Living Single was a fairly popular sitcom starring Queen Latifah that aired for five seasons on FOX in the mid-nineties. In this 1995 episode, the characters appear on a sleazy daytime talk show about “Roommates from Hell”. At the 5:57 mark of this clip, playing the role of “Roommate from Hell#1” and reciting one whole line of dialogue is none other than an unknown Will Ferrell!
