Leonard Nimoy had his guest episode of "The Big Bang Theory" last year, and now another "Star Trek" legend is getting in on the action.

William Shatner teams with "Big Bang Theory" star Kaley Cuoco in his newest Priceline ad, which begins airing Jan. 14.

In the ad, Shatner's character The Negotiator -- whose fate was left in question last year when he was dropped off a bridge in a Priceline spot -- drops off his daughter with a monk to learn the ancient art of negotiating.

Twenty years later, Shatner drives back to retrieve his spawn after her rigorous training period, and that little girl turns out to be ... Kaley Cuoco.

“It’s definitely exciting working with Bill, and being part of a campaign and a brand that I've pretty much grown up with,” Cuoco said of the collaboration. “He has single-handedly built the Priceline Negotiator into a pop culture icon.  I think there's a lot of overlap in our fans, who will appreciate seeing us together as a father and daughter team.  And who wouldn't want to be William Shatner's daughter?”

Who, indeed?
