Greyhound–Yes, the Bus Line–Goes Metal with their New Commercial

There’s no such band as “MuttonGut”–but if there were, they’d travel by Greyhound.

This brings back memories of Burger King’s Slipknot-like Coq Rock.  (Slipknot sued over this ad the case was eventually dropped.)

And who could forget the Ozzy/Justin Bieber Super Bowl ad?
