Hit 'em over the head with a beer can or turn up the hit list as loud as you want, that grain grippa ain't gonna wake up for nobody.

2.
Mythical creature known for it's bow legs, unique gait, long middle fingers, and dangerous mandibles.

It's been said that the Robtor often makes its presence known by a loud scream of its own name in the highest of possible pitches. Such a call has been known to inspire similar such calls by those around it and is also used to summon the Robtor at any moment. Generally unorthodox behavior ensues following such an appearance.
Person 1: "Robtor!"
