This short film starts with the band and ends with the band. In-between we hear them play a song, most likely especially written for the film while we see Danny McBride almost unrecognizable with a huge beard and cowboy hat as the new roadie to the band. It kinda feels like a too long music video.
I don't think it was particularly funny or creative. Funnyordie has done much better on many occasions, even when they don't have famous actors like Black or McBride, who was just done with his famous show Eastbound & Down, when he participated in the shooting of this short movie. This one deserves a pass unless you're a big fan of any of the actors or the band.
