I’ve never watched an episode of It’s Always Sunny in Philadelphia, but if you’re a fan, this commercial will probably delight you. In 1998, Rob McElhenney played a douchebag who attempts to steal his best friend’s girlfriend, but she ultimately decides to stay with her boyfriend after he brings her a bottle of Yoo-Hoo. If that wasn’t enough, the spokesman at the end of this ad is Brian Unger, who would go on to play “The Attorney” on several episodes of It’s Always Sunny in Philadelphia.
