Beer Cat 

Is a game invented by Stephen Colbert where you strap a beer to a cat in a humane way then try to drink the beer while avoiding scratches from the cat. Goggles are suggested for prolonged use.

Jims Beer Cat skills have really improved since he joined that frat which promotes humane animal rights.
