'Jersey Shore' Cast On 'The Ellen Show': Snooki, JWoww And Deena Don't Know What A Caucus Is (VIDEO)

The "Jersey Shore" gals dropped by "The Ellen DeGeneres Show" on Thursday morning to promote the Season 5 premiere of their hit MTV series. Ellen couldn't resist the opportunity to test the guidettes' political knowledge -- and to drop them off her Know or Go machine.

Perhaps not surprisingly, JWoww, Deena and Snooki got caught up on a few of the tough questions, but perhaps the biggest political gaffe came when JWoww confused the word "caucus" with "carcass."

"You mean the part of the body?," JWoww asked. "A caucus," replied Ellen. "A carcass? I'm from Jersey here. There's an accent," JWoww said.

Meanwhile, Deena, Snooki and Sammie were equally as stumped by the question. After JWoww lost her round, Deena had to help her fellow "meatball" through another question: Who was the 44th President of the United States?

Ellen tried to help the guidette by asking, "How many have we had?" Snooki's response? "150."

The cast of "Jersey Shore" may not be the smartest when it comes to politics, but at least they're always good for a laugh.

Watch the clip below. Season 5 of "Jersey Shore" premieres Thurs., Jan. 5 at 10 p.m. EST on MTV.
