Only on the "CBS This Morning" podcast, Norman Lear, the Emmy-Award winning television producer behind shows including "All in the Family," "The Jeffersons," "Maude" and "Good Times," joins his daughter, Kate Lear, and son-in-law, CBS News' Dr. Jon LaPook, to share the comedians and celebrities that shaped his humor and career. He shares how Carl Reiner and Mel Brooks came up with their famous "2000 Year Old Man" comedy routine while they all summered together on New York's fire island. Lear also talks about rehearsing with Dean Martin and Jerry Lewis above a bakery in New York City. Plus, he praises the unmatched comedic timing of Bea Arthur, who starred in Lear's "Maude," and later in "Golden Girls," and why Nancy Walker was perhaps the funniest person he ever met.
