Metalocalypse - Season 1 - Eps 6: Dethfam
Uncomfortable and embarrassed, Dethklok painfully endures while their parents are in town for a visit. They are at first pissed and doubtful when their parents announce the release of the 'Parents of Dethklok' album, but soon realize the depth of their parents' anger. The guys learn an important lesson: there's nothing more brutal in this world than raising children.

Synopsis
Part-American, part-Scandinavian death-metal band Dethklok has a lingering effect on its fans, who take the words seriously and do anything Dethklok lyrics say. The government fears the band's influence and sets out to destroy it by covert means; for example, by sending military pharmaceutical psychotropic drug manufacturers. Deemed sociopaths for tossing hot coffee at their concert attendees, two of the band members are alcoholics, and they all have self-esteem issues.
