Zach Galifianakis pits Jennifer Aniston against Tila Tequila

A mystery guest crashes 'Between Two Ferns.' (FunnyorDie.com)

A new episode of "Between Two Ferns" is out and, as per usual, good for a few awkward giggles. This time host Zach Galifianakis, king of awkward, welcomes Tila Tequila, queen of manic tweeting. Interestingly, Tila comes off as relatively normal when sitting next to Zach.

But, hold up, a surprise guest crashes the interview. What the heck, we'll go ahead and spoil it for you: It's lovable Jennifer Aniston, just in time to promote her new comedy, "Just Go with It."

Warning: There is one itty bitty NSFW moment -- specifically two little itty bitty words that, taken alone, are perfectly innocuous, but when uttered together, constitute something you probably wouldn't want your boss or your kids to hear blaring from your computer. Watch at the link.
