So you might be wondering, "what the heck does Guitar Hero have to do with Supersized Meals?". Well, everything when Guitar Hero is being played by a giant Pizza! Why a giant Pizza? I've got no idea. Maybe someone left the car running with the garage door closed...

Now you can't say you've never seen a giant slice of pizza playing guitar hero with a double neck controller. The controller was built from 2 regular controllers and the pedal is modded to make it possible to play both guitar parts from one neck.
