The modern alternative spelling of "a lot".
When asked by his editor why he always spelt alot as one word, Dave wrote back:
"See, you are a prisoner of the English language and I am a language pirate. You are the British with their stuffy coats and large boring navies and I am sailing the high seas of the language with my crew in a fast, nimble ship evading you at every moment plundering the language for the good of the reader and keeping the written sea free of your rules. I've hoisted my flag and given you my finger. Alot."
