King of the Hill was an animated television series made by 20th Century Fox.
- Although it was not mentioned in dialogue, Gibson was watching the episode "Shins of the Father", from King of the Hill's first season. The creators of King of the Hill had hoped Robert Patrick would voice the character of Dale Gribble (the character was modelled slightly on Patrick) but this did not materialise.
- The X-Files itself was mentioned by Hank at the end of the second season episode "Traffic Jam".
