My theory?
Roverfish drives out to East Bumblefark, Washington with all the good intentions of relaxing, soaking in the sun and enjoying the great outdoors. As he is wont to do, he imbibed in various adult beverages throughout the weekend, realized that his supply was running low and ventured into the neighboring town for reinforcements. While shopping for supplies, a local townie gave him the stink eye and invaded his personal space. Never one to back down, Fish takes him outside, engages in some heavy pushing and is arrested by the town sheriff, who also happened to be the guy he was fighting. Sheriff books him on public intoxication, assault, battery, tax evasion and littering.
Close?
