Snooki's Nerdy Twin Sister Joins 'Jersey Shore' On Kimmel (VIDEO)

The one and only Nicole "Snooki" Polizzi was the guest on "Jimmy Kimmel Live" last night promoting her book (yes, book) and also found the time to make this funny sketch. During the monologue, Kimmel sets it up as a look at the newest "Jersey Shore" cast member, Snooki's nerdy twin sister, Franki "Four Eyes."

Donning nerd glasses, a high-waisted skirt and lacking both her signature pouf and cleavage, Snooki plays her dorky twin sister with surprising hilarity. Check it out and tell us what you think of Snooki's acting skills in the comments.
