After watching the Saturday Night Live skits featuring Sarah Palin (the real one, not the Tina Fey one) I realized, she's mostly just sitting or standing there. In other words, Palin plays the same role on SNL that she does in real life, that of an accessory.
Here she is on the opener to the show. All the (what passes for) funny lines are those of Alec Balwin's.
And here she is on the Weekend Update segment, where she sits and dances to a rap that Amy Poehler performs.
I have to say, though, kudos to the Arctic Cat shoutout with the snowmobile gear. I'm from the home of the Arctic Cat snowmobile.
