The first North American leg of Slayer's farewell tour — featuring support from Lamb of God and Behemoth — wrapped up last night (June 20th) in Austin, Texas. In commemoration of the trek's conclusion (it resumes next month, with Behemoth absent from the bill), the Polish metal act pulled a prank on Randy Blythe and Co., as shown in the following video from frontman Adam "Nergal" Darski.
Partway through Lamb of God's set, the group donned lamb masks and pranced around the stage, and one point, appeared to partake in a game of "Ring Around the Rosie." To make matters weirder, Blythe got in on the dancing himself, busting out some polka moves in spite of his evident confusion. Now that's what we call being a good sport. Watch below.
