Palin To Be On SNL??

I'm excited. This is the first time I'm posting something that has been in very limited circulation on the web. Fox News reported today that Sarah Palin may be on Saturday Night Live soon, though Lorne Michaels wasn't specific as to how or when. Later, SFGate reported the specific detail that she will be spoofing Tina Fey's American Express commercial and that it will happen on the 18th, but the site doesn't show any sources so for now this part seems like a total rumor.
