My Darwin fish eats your Jesus fish damns the pot-smoking jam band Phish fish. Orrr...my TRUTH ichthys consumes your Darwin decal. Presumably with love. And with Star Trek and Cthulhu fish as spectators. The Flying Spaghetti Monster will be along shortly. Except in Kansas, where there is a bounty on his head.
SMBC's Gulpo is the car decal that eats car decals. Or, more poignantly, the fish who eats concepts. Because although my morning commute is as enriched as the next guy's by knowing the faith (or lack thereof) of the Honda that sped past me, cut into my lane, and then slowed down 10 mph, this broadcasting of belief systems that should be reserved for the dinner table and the shooting range could probably stand a Gulpo hip check.
Then again, one could argue the would-be cleaner fish sent to end the madness of metaphysical debate just perpetuates it. I'm hesitant to do that because it requires a lot of thought and stringing together of coherent words. But if you're so inclined, go ahead and have a go at Gulpo in the Comments section below.
