The Big Bang Theory’s Kaley Cuoco isn’t very impressed with her upcoming co-star William Shatner.

The actress, who plays the Star Trek alum Negotiator’s daughter in new ads for Priceline.com, has some fun with her new co-star in an exclusive behind-the-scenes video for the travel service’s new campaign.

Acknowledging that her Big Bang co-stars — including Jim Parsons, Johnny Galecki, Simon Helberg and Kunal Nayyar — are big fans of the beloved geek god, she asks Shatner to autograph some photos. While the face of Priceline is thrilled to do so, his exuberance is short-lived when the two-time People’s Choice Awards host declines to want one for herself.

“The Negotiator harbors many secrets, and this is just one of them,” Shatner said of Cuoco’s casting as his daughter. “It’s another layer to the enigma of the Negotiator that shows us there are many different ways to find great hotel deals. And, as in life, there is something new he can learn from a younger perspective.”
