writer, director, producer, Judd apatow, the man behind "Freaks and geeks," "40-year-old virgin." "Knocked up" just to name a few. New project near and dear to his heart that honors his longtime mentor called "It's Garry Shandling's book" and we welcome you, Judd. Thank you. Like you I'm a giant fan of Garry Shandling. Three years it's been since he passed away. Yes, yes. Amazing. Starred in "The Larry Sanders show." Gave you one of the first breaks. What is your favorite personal memory of Garry and why did you feel like you needed to share it with everybody. We had a psychic on the Larry Sanders show like a guest and the psychic said to me you're going to direct soon and then like two weeks later Garry walked in my office and said you're directing the next one and that was the big break of my career was Garry asking me to direct the show. So believe in psychics. I don't know about that advice. So an amazing mentor and friend awe put the book together and came across all these -- it's sort of like a scrapbook and came across this stuff in kind of a cool way. Well, after he passed, you know, we had to go through all of his things and I thought he wasn't sentimental and didn't save anything because there was nothing out in his house and I would open closets and it would be filled with boxes and he saved everything. Wow. So there were no pictures like of his family around and you open a box and there would be like 600 pictures of his family. So nice. And sharing that with everybody who gets to see these stories but you got to know him in a really personal way. A lot of comedians say he is one of the greats. Yes. What was it about him? Such a comedian's comedian. He was just a very soulful person. He was really neurotic but was trying so hard to drop it so like "The Larry Sanders show" is about a guy who has a giant ego and I think Garry hate tlad part so created a show about people would were obsessed with fame. There is a quote in the book where he says, quote, maybe comedy is a gift you give to people. This is to this point. Maybe comedy is a gift you give to people to help them through this impossible life with no intention of getting anything in return and he graciously helped you as some of the funniest moments in one of your funniest films, "The 40-year-old virgin." Tell us about that. Well, he -- I had him read the script and he said, you know, Judd, at the end you have to show them do it and I was like, I don't think I can and he's like, no, you have to because you have to show that they're in love and because they're in love it's better than when their friends do it so you have to show it. I don't think I can show it and then one day Steve carell said, well, maybe at the end I just sing a song and that's how you know and it was all because Garry was bothering us to figure it out. So he guided you in some pivotal moments of your life and now look at you. Your daughters are both acting. Your daughter Maude, you were just listing off how many things she's in. "Euphoria." Doing so many projects and also said that she wants to be like her dad and direct and write. Yeah, I'm very -- you know, proud of her. She's on "Euphoria" and she plays the good girl and I was nervous because she left college and then I realized that I had put away $10,000 a year her entire life to pay for college and that by quitting I had made $130,000. I didn't know you could get that back. It was a big windfall for me. So you approve of the career choice. Yes, it's worked out. And Irish, your younger one is following in your footsteps. A real family affair. Amazing. Thank you so much for sharing this book with us. Garry Shandling is the best and so are you. Love your family. "It's Garry Shandling's book," it comes out tomorrow, everybody.
