"This is a true story, told by Robin many years ago.... Stern went on a Central Park picnic with his first wife Alison and his then very young daughters. A male fan recognized him and began running toward him. Stern, thinking it was an attack, panicked and quickly locked himself in the family car, LEAVING HIS WIFE AND CHILDREN ON THE OUTSIDE! I know this is a true story because when Robin told it live on the air, Stern became very angry and at first denied it. He almost immediately went to commercial and after coming back, he did ashamedly admit it was true.... Howard Stern is a gutless, talentless, vulgar adolescent."
There is no backing of evidence, dates. So this is a fairy tale until we get a date.
