Earlier this week, Morrissey pulled out of an appearance on "Jimmy Kimmel Live" because the cast members from "Duck Dynasty" were going to be on as guests. "As far as my reputation is concerned, I can't take the risk of being on a show alongside people who, in effect, amount to animal serial killers," Morrissey said in a statement, sparking a week-long feud between the singer and the comedian.
Kimmel ended up hosting "Duck Dynasty" as planned, then joked on-air about how Morrissey "keeps finding new ways to depress us."
The singer responded by admonishing Kimmel's jokes about depression, healthy eating, gun-ownership and "the notion that animals should be entitled to the possession of their own lives," a cause close to Morrissey's heart as an animal activist and lifelong vegetarian.
