I love how decent and moral and honest Hank is. (Sometimes he can be annoyingly decent, but he's a nice guy.)
I love Hank's dad, Cotton. He's a loudmouthed, mysogonistic, sexist jerk. He's unapologetic, and he feels he has the right to be because he's been through so much. (He lost his shins in combat.) Other than the shin thing, he's the Arlen, TX version of Archie Bunker.
Brittany Murphy does the voice of Luanne.
Kathy Najimy does the voice of Peggy.
But there are so many other great actors / actresses that have done guest spots as well:
Debra Messing, Reese Witherspoon, Renee Zellweger, Anna Faris, Danny Masterson, Topher Grace . . . . . I swear, you look at the cast for any given episode, and you're going, "REALLY!?! They were in that?"
These are my favorite episodes:
Fun With Jane and Jane - Luanne gets accepted by a college sorority that is actually a cult, while Hank and his friend has to shoot emus for Buck Strickland.
Keeping Up With Our Joneses - When Bobby is caught trying a cigarette, Hank decides the proper discipline is making Bobby smoke an entire carton. The result sparks an old smoking habit of Hank's and Peggy's, as well as a new habit in Bobby.
Pretty, Pretty Dresses - During the Christmas season, Bill becomes suicidal and his friends have to watch him. Things take a bizarre turn when he decides to become his ex-wife Lenore.
Luanne Virgin 2.0 - Luanne joins a church group to become a "born-again virgin," where Peggy reveals a shocking fact about her past.
The Bluegrass Is Always Greener - Connie plays the fiddle in Hank's bluegrass band, but keeps it a secret from her father, who wants her to go to Van Cliburn's violin academy.
Hilloween - Junie Harper, a conservative church member, declares that Halloween is a Satanic holiday, and gets the school to shut down Hank's "Haunted House" on the grounds that it violates the separation of church and state. Luanne and even Bobby start to believe Junie when she says that Hank is a Satanist, and Hank has to fight against Junie's attempt to cancel Halloween for the whole town.
