"So I start reading it, and I'm laughing while I read it, and (wife) Sarah (Michelle-Gellar) goes, 'What are you reading?' And I'm like, 'You wouldn't believe me if I told you,' " he shares.

The first season of the new show is airing now on U.S. streaming service Peacock.
Sarah Michelle Gellar is also preparing for a TV return after taking a step back for several years.
She's also among the cast members of another new TV show "Other People's Houses", which reunites her with the "Ringer" writers Eric Charmelo and Nicole Snyder.
