fluffy This and Code Monkey were the first John Coulton songs I ever heard, and are probably the two best songs he's ever written. Not really digging the video part so much though.
Syd Midnight I would just like to point out that 4 years ago, I was banned from PoE Chat because it was decided that Johnathan Coulton was "zzz who cares" and "nobody gives a shit about" John Hodgman "you boring fag". Nobody even checked out my links.
I learned a lot about interacting with chat. Like, don't.
