For Isaac

I was talking to my friend Zak today and he said he was wearing his Dogs and Water t-shirt ("not on purpose" he said) and he said his son Isaac asked him what does it mean. So he said he would ask me. I said I didn't think that I was under any obligation to explain the complex symbology of my self expression to a six year old. But he said that probably wouldn't be good enough. So this is my best guess.
