Did you know that most of the radio call-ins on 90s sitcom "Frasier" were actually big celebrities? Thanks to this video that was first posted on Reddit and went viral over the weekend, a lot more people probably do.
The many folks who phoned into Frasier's radio show with various degrees of mental illness weren't just Hollywood voice-over actors. They were actually Christopher Reeve, Art Garfunkel, John Lithgow, Matthew Broderick, Ray Liotta, Ron Howard, Bill Paxton, Helen Mirren, little Hillary Duff (you can hear her at the very end) and more.
Watch out for Macaulay Culkin calling in as a man mocked for his childlike voice, Roz hitting on Kevin Bacon and Cindy Crawford calling in as "Bill," who is undergoing a certain "transition." As the YouTube description points out: "BONUS: WATCH HIM AGE"
