Sit com show connections

[Birdbrain]

The soda mr. Pib was a soda on American dad that Stan and Francine tried to save.

The same name of the soda was also mentioned on king of the hill

Hank and Peggy from king of the hill started as two characters on the bevis and butthead movie bevis and butthead do America

There was a spin off from bevis and butthead that stared one of the characters on the show Daria

My question is...how far can we stretch these connections both from the beginning connection on and from the ending connection on?
