You're part of a young cover band. You often perform at a popular bar, but today.. you're the rhythm guitarist of the band. You look around the room and see Ozzy Osbourne and Zakk Wylde there. Your throat is dry. But it's time to start the show. Everything is going well until Zakk and Ozzy decide to.. come up on stage with you?! Yeah.

Ozzy says something to your singer and pats him on the shoulder, and Zakk comes up to you.

"Let's play together? You're the rhythm, I'll play the lead. You can do "Crazy Train", right?"
