On May 25, 1992, Jay Leno made his big debut. Since then, he went on to tell hundreds of thousands of jokes for more than 20 years.
Many of those jokes were written by Jon Macks. Macks is one of only two writers who was with Jay Leno for the full extent of his late night career.
Macks wrote about those experiences in his new book "Monologue: What Makes America Laugh Before Bed," and he joined host Alex Cohen with more.
