Things always get a little weird when the Hot Country Knights are around, and Friday night (Feb. 22) in Nashville was no exception. Dierks Bentley's '90s country cover band opened the 2019 Burning Man Tour stop at Bridgestone Arena, bringing out Thomas Rhett and some other special guests to add to the madness.

Sporting their best '90s gear -- mullets included -- Bentley and his band, as the Hot Country Knights, got the night started with a set of old-school country music and onstage shenanigans. Rhett, also dressed appropriately for the occasion, joined them to perform "That Ain't My Truck," made famous by his father, Rhett Akins.

A Top 5 hit for Akins, "That Ain't My Truck" was co-written by the artist with Tom Shapiro and Chris Waters. As Rhett, Bentley and crew ended the song, they were joined onstage by Bentley's daughter Jordan, who drove out in a kid-sized truck while sporting a leopard-print top and mullet of her own, just like her daddy.

After unceremoniously kicking Rhett offstage, Jordan passed out roses to fans in the front row and joined her dad for a song. Readers can press play below to watch the ... well, what can only be described as pure ridiculousness.

The Hot Country Knights' Friday night set also featured a cameo from Sawyer Brown lead singer Mark Miller. During the show, Miller joined the band onstage to perform his group's hit "Some Girls Do," gamely playing along with the Knights' shenanigans. Press play below to watch the moment.

Bentley had a number of special guests waiting in the wings at Bridgestone Arena: During his headlining set, he invited Keith Urban out to play guitar during "The Mountain." Urban then stuck around as Miranda Lambert joined the two country superstars onstage; together, the three performed an impromptu medley of classic country songs.

Bentley's 2019 Burning Man Tour features Jon Pardi and Tenille Townes, as well as the Hot Country Knights, as special guests. He recently extended the tour through the summer.
