The Amazelingtons

Now-dead rock band that once featured band therapist Dr. Johnathan Twinkletits (it's pronounced twink-LET-its, so stop snickering), who killed them when he was fired.

They are mentioned in the "Performance Klok" episode of animated comedy Metalocalypse (first aired 17 Sept. 2006), where Twinkletits has been hired to help the band get through interpersonal differences, before attacking them in a rage and being then fed to wolves.

Twinkletits also appears in the "Cleanzo" episode, having survived having his arms eaten off by wolves (he got cool new robot arms!).
