Booth (David Boreanaz) and Brennan (Emily Deschanel) will once again be going undercover, this time posing as contestants at a ballroom dancing competition.

As first reported by TV Line, Mary Murphy and Tyce Dirorio from the Fox hit So You Think You Can Dance will appear as judges during the episode. Murphy has been a judge on the show since its beginning, but became a permanent judge for Season 3. Dirorio has choreographed for the show along with being a choreographer for pop stars like Janet Jackson, Paula Abdul, and Jennifer Lopez.

The pair has gone undercover several times over the course of the seven seasons, even appearing as clowns in one memorable episode.

As reported by TV Line, another recently announced Season 8 guest star is Army Wives actor Brian McNamara. McNamara will play a pet expo proprietor. Executive producer Stephen Nathan has said he hopes to highlight the horrifying practice of keeping exotic pets in the United States.

Do you think Brennan and Booth have the moves to pull it off? What’s your favorite undercover episode from Bones? Do you think Mary Murphy will use her signature phrase “the hot tamale train” in the episode? Who else would you like to see guest star this season?

Be sure to catch the next episode of Bones on Monday at 8 pm EST.
