Source for comics quote?

[nancylebov]

I just saw an icon of "Advancing on me will only bring you closer to the cold wrath that is my spork!". While enough other people have recognized the brilliance of the line for it to show up a few times in google, the comic it's from isn't mentioned.

The icon is a ways down this comment thread.

Motto: I found my popular culture had become unmanagable.
