Continuity mistake: As Jack and Kyle are walking up the "Guitarway to Heaven" in the Rock Museum, they vary between marching completely in synch with each other and out of synch. They are still walking directly next to each other, so it is not due to one of them changing their pace.

Ending / spoiler
Directed by: Liam Lynch
Starring: Ben Stiller, Jack Black, JR Reed, Kyle Gass, Ronnie James Dio
JB and KG have a rock off with the devil in which if they lose the devil will get to take KG back to hell to be his "little @$&%$." They win and the devil's horn is cut off so he is not complete and has to rteurn to hell. They take back the horn to their apartment in which they turn it into the bong of destiny and use it to write songs.

Trivia: Troy Gentile plays young JB (Jack Black). In his previous role, "Nacho Libre" Gentile played young Nacho, who was played by Jack Black. Incidentally, "gentile" means one who is not Jewish, and Jack Black was born and raised Jewish.
