Rhett McLaughlin and Charles “Link” Neal, a best-friend comedic duo that goes by Rhett and Link, are best known for hosting the daily Internet talk show, “Good Mythical Morning” and are getting ready to release the second season of their YouTube Red series, “Rhett And Link’s Buddy System.”

The new season will premiere on Wedneday, Nov. 29, releasing all eight episodes in one go for easy binge-watching. Within the all-new episodes, Rhett and Link will be joined by a slew of celebrity guests.

“Veep” and “Arrested Development” star Tony Hale, “The Big Bang Theory” actress Mayim Bialik, “24” alum Mary Lynn Rajskub, “Ballers” actor Rob Corddry and “Anchorman” star David Koechner will all be guest stars in the new season. Also, “Popular” alum Leslie Bibb, who was in the first season of the series, will be returning for Season 2.

On top of that star power, also joining the cast are Michael McDonald (“The Heat” and “MADtv”), Page Kennedy (CBS’ “Rush Hour”), Garrett Morris (“2 Broke Girls”) and Alison Rich (“Angie Tribeca”).

“Season ​2 ​of ​‘Buddy ​System’ ​seeks ​to ​explore ​Rhett ​and ​Link’s ​powerful friendship ​in a ​new ​and ​refreshing ​way ​by ​asking ​the ​radical ​question: What ​if ​Rhett ​and ​Link ​had ​never ​met ​in ​1st ​grade and went on to become hosts of the popular internet show ‘Good Mythical Morning,’” the official synopsis asks. “​The all-new episodes take place in ​a ​parallel ​universe, where instead ​of ​growing ​up ​together ​in ​North Carolina, ​they ​meet ​as ​adults ​in Los ​Angeles after Link is forced to move into Rhett’s empty top bunk. ​Will they each be able to grow enough of a friendship to form the ‘buddy system’ their counterparts enjoy in this universe?”

The new season is directed by Steve Pink (“Hot Tub Time Machine” and “Children’s Hospital”) and is executive produced by McLaughlin, Neal and Stevie Wynne Levine, along with Jason Berger and Amy Laslett.

Michael Jamin and Sivert Glarum (“Maron,” “King Of The Hill”) are joining the series as showrunners.

All eight episodes of “Rhett And Link’s Buddy System” will be available to stream on YouTube Red on Nov. 29.
