The TV show King of the Hill is still considered one of the most beloved animated series of all time. The FOX series, created by Greg Daniels and Mike Judge, ran for 13 seasons through the 90s and early 2000s, and there have even been rumors of a potential reboot. The citizens who live along Rainey Street in the fictional town of Arlen, Texas are completely hilarious and part of that can be credited to the stellar cast who brought them to life.
Hank Hill (Mike Judge) and his wife Peggy Hill (Kathy Najimy) along with their son Bobby Hill (Pamela Adlon) led the series with a slew of supporting friends and neighbors -- Bill Dauterive (Stephen Root, also the voice of Buck Strickland), Dale Gribble (Johnny Hardwick), Joseph Gribble (Breckin Meyer), John Redcorn (Jonathan Joss), we could go on and on. One of the fun things about the sweet show was that it became so popular, a ton of celebrities and musicians wanted to get involved with small guest star roles.
We've rounded up 12 of the best guest stars to ever grace the series. The show is currently streaming on Hulu so make sure to go back and watch these episodes if you need a good laugh!
1. Brad Pitt
Potentially one of the most iconic guest-starring appearances was when Brad Pitt showed up to play Jeff Boomhauer's brother Patch. Season 8 Episode 1 "Patch Boomhauer" is completely hilarious, showing the sibling rivalry of the Boomhauer brothers after Patch comes to town to marry his brother's ex.
2. Tom Petty
Technically way more than a guest star, but we have to include Tom Petty's character Lucky who plays the boyfriend of Hank and Peggy's niece Luanne Platter (Brittany Murphy). After being a major fan of the series, Petty came on for an episode but had so much fun he told Mike Judge he'd be happy to come back again.
"I loved the show long before I did it," Petty told IGN in 2007. "And it was a complete coincidence that I got called, because it was really one of my favorite shows."
"He said, 'Anytime you want me to do it, I'll do it," Judge noted. "Turns out he really meant it."
Writers loved Petty's acting so much they started creating episodes completely around the character of Lucky. "It was because he (was) good. He came in and he was a really good actor," explained Pamela Adlon. "If (Petty) sucked, then there would be no Lucky."
3. Snoop Dogg
In Season 5 Episode 13, "Ho, Yeah!" Snoop Dogg appeared as the character Alabaster Jones. Hank and Peggy take in their friend Tammy (Renée Zellweger) and even help her get a job with Hank at Strickland Propane. But pretty soon her pimp shows up and thinks that Hank has been trying to steal one of his girls.
4. Trace Adkins
In multiple episodes, country singer Trace Adkins voiced the role of the redneck Elvin Mackleston. Coincidentally, his first episode was also the same episode that introduced audiences to Tom Petty's character Lucky.
5. Willie Nelson
In episode 4, "Hank's Got the Willies," Bobby accidentally hits country singer Willie Nelson with a golf club on a local course. Of course, there's drama involved as Nelson is Hank's hero. In real life, Willie Nelson owns a golf course outside of Austin, Texas, so this seems to be a specific nod to the Lone Star State's capital. It's also the location of Rainey Street which Mike Judge used as the main character's street in the series.
6. Randy Travis
Potentially one of the best Peggy Hill episodes of all time is when country singer Randy Travis steals her music. Season 4 Episode 24, "Peggy's Fan Fair" follows the Hill family attending a country music festival in Nashville. No one believes poor Peggy when she says that Travis stole a song that she sent to him in the mail and it's truly hilarious. Numerous other country stars make an appearance in the episode as well including Brooks & Dunn, Clint Black, Wynonna Judd, Terri Clark, Charlie Daniels, and Martina McBride.
7. Matthew McConaughey
In Season 3, Episode 14, "The Wedding of Bobby Hill," native Texan Matthew McConaughey shows up to play a ridiculous concert promoter dating Luanne, Rad Thibodeaux.
8. Kid Rock
In Season 7, Episode 2, "The Fat and the Furious," rocker Kid Rock plays himself. The episode is centered around Bill discovering the world of eating competitions after participating in a local hot dog eating contest.
9. Charlie Daniels
In Season 6 Episode 9, "The Bluegrass is Always Greener," Charlie Daniels comes back to play himself in this episode all about Hank's bluegrass band. He recruits Connie, a talented violin player, to join his band and participate in a bluegrass competition. He and the boys lie to Charlie Daniels saying that Connie's dying wish is to meet and play with him so he plays with the band on stage.
10. The Chicks
In Season 4 Episode 6, "A Beer Can Named Desire," Bill travels to New Orleans to meet his extended family. Oscar-winner Meryl Streep appears as his Aunt Esme and The Chicks -- Natalie Maines, Emily Robison, and Martie Maguire play his cousins.
11. Johnny Depp
In Season 8 Episode 20, "Hank's Back," Hank starts taking yoga classes after hurting his back at work. Musician and actor Johnny Depp guest stars as the ridiculous yoga instructor Victor who might be way too zen, but is still trying to help Hank feel better.
12. Vince Gill
Country star Vince Gill appeared in two different episodes of King of the Hill. He was the only major country singer to play someone other than himself in "Peggy's Fan Fair," where he played Assistant Pastor Larry. He also came back for "The Bluegrass is Always Greener" where he was the singing voice for Boomhauer. An unexpected surprise for fans of the show that the character could sing since he's well known for his bumbling, hard-to-understand voice.
