Zakk Wylde may already have a career as a world-renowned guitarist but that doesn't mean he wouldn't necessarily want a job with the World's Strongest Coffee. After begging and begging us to hire him, we decided to let him come in for an interview. As you would know if you've ever looked at any of his Instagram posts, Zakk can get a little, well, crazy. Below, watch what happened when the Black Label Society frontman stopped by our headquarters for an interview. Hint: it didn't bode well for our head of production, John. That had to hurt.
