Jaco was mentioned last night on the television series "Bones", Mayhem on a Cross (HD), Season 4: Episode 20, at around the 18:50 mark. The show is about a super heavy metal band and Norway.

How cool is that? It's Jaco who keeps his own legacy alive, no one but he is responsible, needless to say. :-P
