Behemoth and Lamb Of God recently wrapped up their touring duties with Slayer on their farewell tour. Behemoth won't be joining Slayer and crew on the next leg, so they took this opportunity to prank Lamb Of God on stage. Behemoth all put on lamb masks and joined the band dancing on stage during their set, a prank that Randall Blythe didn't initially catch onto but still had a ton of fun.
Watch the video from the prank below.
