Tom Anderson strongly resembles Hank Hill from Mike Judge’s later show, King of the Hill - both were based on the same person from Judge’s youth. In this case, Tom was obviously the inspiration for Hank Hill.
Both characters have an important possession called “Betsy” - Anderson’s is a shotgun, Hill’s is a guitar. The two also have the same voice, except Tom’s is deeper and Hank’s is clearer.
In Beavis and Butt-head Do America, Tom Anderson praises butane gas in a scene, while Hank praises propane (and ironically, Bobby once tells Joseph that Hank says that butane is a “bastard gas”).
Also noted, that in King of the Hill was originally meant that Hank Hill was supposed to be the son of Tom Anderson; however, FOX was unable to get Tom because he belonged to MTV. They had to give Hank a different father, Cotton Hill.
