Because, you dumb sumbitch

Rico says he inserts serial commas into other people's words before posting them here.
One, because he can.
Two, because it's the right thing, even if most people don't get it.
Why?
Because, as Rani Cochran (then at Apple with Rico) explained, it all started with a book dedication:

I would like to thank my parents, Ayn Rand and God.

Imagine how differently that would read with a comma after Ayn Rand...
