Welcome, Edbern. Yarr, you mean our Jollyfish! I have one on my car.
It's a response to all of the fundamentalists ostentatiously proclaiming their piety by putting a fish on their car. Well, we have a fish too, but ours is Piratey, with an eyepatch even. It's also a way for Pastafarians to identify each other, while leaving the fundies mystified. Putting a Darwin fish on your car, or the holy FSM himself, might cause over-religious neighbors to take offense, but our Jollyfish does not seem to. At least, nobody's objected to mine so far.
No trinity, just one noodly drunken god with a juvenile sense of humor.
