Palin may appear on 'Saturday Night Live'

... To spoof Tina Fey's impersonation of her, as reported by Bill Zwecker in the Chicago Sun-Times --

"It's looking more and more likely that Alaska Gov. Sarah Palin will appear on ''Saturday Night Live'' -- to have some fun with Tina Fey ... Some key McCain staffers are content with Palin joking about the "SNL" routines on the campaign trail -- as when she scribbled "I'm not Tina Fey" on a supporter's cell phone and said she'd dressed as Fey on Halloween. But others -- including the governor herself -- think a return punch on the NBC airwaves is what's needed. ...
... I'm hearing some sort of Palin tweak of Fey's American Express commercials is in
the works. While next weekend's ''Saturday Night Live'' will be a rerun, it is possible Palin could appear Thursday on the first of NBC's ''Weekend Update'' specials in prime time."
