'Graceland': Briggs And Charlie Practice Their Best 'O-Mouth' (EXCLUSIVE VIDEO)

You've got to fake it to make it on USA's "Graceland," and in Thursday's episode, Briggs (Daniel Sunjata) and Charlie (Vanessa Ferlito) have to sell the euphoria of a heroin high to keep their cover -- in fact, their lives depend on it.

As HuffPost's exclusive preview clip illustrates, the secret to faking a high is to perfect the art of the "O-Mouth," which also happens to be the title of this week's episode. Check out the risque clip above, in which Mike (Aaron Tveit) catches his fellow FBI agents in a compromising position. (Or does he?)

Read the episode description for "O-Mouth" below.

While Mike gets deeper into Bello’s organization, Briggs and Charlie resume their former identities as a sexually-charged couple to get intel on a mysterious drug supplier called Odin.

"Graceland" airs Thursdays at 10 p.m. ET on USA.
