Zach Galifianakis' beloved Funny or Die show, 'Between Two Ferns,' returned on Thursday with guests Jerry Seinfeld and Cardi B, and the hilarious episode had Galifianakis epically roasting the comedian.
Benedict Cumberbatch, Ben Stiller, John Goodman and Chris Rock were only a few of the other A-listers who stopped by for 'Saturday Night Live's big season finale.
ET spoke with Seinfeld as he helped celebrate the release of Bob Roth's new book 'Strength in Stillness: The Power of Transcendental Meditation,' which is available now.
