It’s an Elvis joke. Elvis was known as The King. The show has the word “king” in the title. Fuck you.

King of the Hill has been canceled. I’ve known a few people who have loved this show and will no doubt be heartbroken, but upon reading the news my first reaction was, “This show is still on?”
As an unrelated (so far as I can tell) addendum, the article informs us that American Dad will live on into its fifth season. It’s a great show—no matter what everybody in the world who isn’t me says—and I’ll be interested to see the direction it takes under a Democratic president. (Stay tuned!)
