Comedian Arj Barker has appeared on Late Night with Conan O'Brien, The Tonight Show with Jay Leno, and Comedy Central Presents, among others, but is probably best known as Bret's and Jemaine's friend Dave on Flight Of The Conchords. He also co-wrote and performed in the critically-acclaimed off-Broadway show The Marijuana-Logues. What does LYAO mean? It's simple - laugh your ass off! And you're bound to do that with this performance.
