* CrowningMomentOfFunny: Her Palin impression in general, but especially her appearance on the 2010 Night of Too Many Stars telethon. One of the prizes for donating a lot of money was a copy of Sarah Palin's book... autographed by Tina Fey with the message "I didn't write this" written inside.
* MemeticMutation: She's the one responsible for the "I can see Russia from my house!" meme, [[BeamMeUpScotty not Palin]].
** Technically, Seth Meyers is the one responsible for the line as he was the writer of that particular sketch. Meyers and veteran ''[=SNL=]'' writer Jim Downey were actually behind the Palin sketches, with Fey contributing a line here and there between rehearsals (one contribution she owned up to was, after noticing Palin had a distinct way of pronouncing the letter "R," told the writers to give her lots of R's to dig into.) This confusion has become a bit of a CowboyBebopAtHisComputer situation thanks to journalists who assume that because Tina appears onscreen in something, she must've written it. (This rule also applies to her films, to a certain extent, particularly ''Baby Mama'' and ''Date Night''.)
* NauseaFuel: Tina loves doing this to her own photo shoots. You will get to see Tina's face. Making any sort of assumption about what is ''below'' that face, though, is taking your life into your hands. Perhaps it will be Tina's body. Perhaps it will be Tina's body with a large amount of prosthetic fat attached. Perhaps it will be Justin Beiber's body.
