Sarah Palin's Most Memorable TV Moments (VIDEO)

Variations on the expression, "I can see Russia from my house," have become so common that it's hard to imagine it's only been a year since Sarah Palin catapulted onto the national scene when John McCain announced his decision to make her his running mate on August 29, 2008.

Since then, the former Alaska governor has become one of the country's best-known politicians, consistently named one of the top three choices for Republican presidential candidate in 2012, an object of ridicule to some, and an easy punchline for late-night comics.
