Sarah Palin is officially a legend! Hustler Video is shooting a porn with a look-alike titled "Nailin' Paylin." The spelling is sic and so is Hustler. You betcha!

The faux Sarah is Lisa Ann, who "will be nailing the Russians who come knocking on her back-door." In another scene -- a flashback -- "young Paylin's creationist college professor will explain a 'big bang' theory even she can't deny!"

There's also a threeway with Hillary and Condoleezza look-alikes.
