Before Paar, Carson, Letterman, Leno and Fallon there was Joe Franklin. The talk show legend and showbiz historian is listed in the Guinness Book of World Records as the host of the longest running talk show in history (43 years and 300,000 guests, give or take) and often credited with inventing the format itself. Gilbert and Frank dropped in on Joe's infamously cluttered (an understatement!) Times Square office to nosh on chicken salad, dodge falling stacks of collectibles and ask the "King of Nostalgia" about his memories of Charlie Chaplin, Woody Allen, Buster Keaton, Frank Sinatra, Barbra Streisand and John Lennon (to name but a few).

Comedian and actor Gilbert Gottfried, a man Stephen King once called “a national treasure,” talks with the show business legends, icons and behind-the-scenes talents who shaped his childhood and influenced his comedy. Along with co-host and fellow pop culture fanatic Frank Santopadre, Gilbert is joined by comics, actors, musicians, talk show hosts, writers and other eyewitnesses to Hollywood history, including Bruce Dern, Chevy Chase, “Weird Al” Yankovic, Adam West, Steve Buscemi, Micky Dolenz, Jim Gaffigan, Judd Apatow and DOZENS more, for a funny, frenetic, fly-on-the-wall look at showbiz then and now (but mostly then.) Gilbert Gottfried’s Amazing Colossal Podcast was named "Best Podcast of 2015" by the Village Voice and one of iTunes' "Best of 2014." It has been featured in Rolling Stone, Wired and the Los Angeles Times.
