This might be a long shot.

On AMC's Mad Men Forums, someone had linked to a Mad Men blog that had funny fanfic type of stuff.

The most notable one was this meme...

Joan walks towards Peggy.
Joan's Boobs:  Hi.
Five Minutes Later
Joan: Hello Peggy.


So does anyone know of this blog?  It could very well have been from Season One, meaning 2007!
