The summer of Dave Grohl continues. Monday night at a Foo Fighters show in Clarkston, Michigan, Grohl saw a fan in the stage holding a sign that said, “It’s My 50th. Let’s Have A Beer.” The Foo frontman took the suggestion literally and invited the man, who said his name was Griffin, up on stage for a cold one.

“I know it’s your 50th birthday,” Grohl said in fan-shot footage from the show. “We’ve got a lot of songs we’ve got to play tonight. I’m gonna share this beer with you, and then I’ve gotta do my job.” He continued, “Griffin went to Office Depot and bought one piece of cardboard and a magic marker. There you go, that’s all it takes.” Then they chugged.

Classic move for a band that’s invited a leg doctor on stage to cover “Seven Nation Army,” Rickrolled the Westboro Baptist Church, and has its lead singer perform atop a light-up throne.
