Okay, I remember reading a fic once, but the only scene I remember is this:
Lois comes to work and finds her co-workers gawping at what appears to be a picture of her posing nude. She tells them it wasn't her, but they don't believe her, so she takes Cat into the ladies' room. When they come out, Cat is shocked and confirms it's not Lois; apparently, somebody just pasted Lois's head onto another woman's body for nefarious purposes.
That's all I remember. Does anyone know which story this was, or what else it was about?
