I never knew Patrick Duffy was the original host of GSN's Bingo America and I would love to hear the story of why Patrick Duffy was replaced by Richard Karn on Bingo America? Was Patrick Duffy very unhappy with the Bingo America hosting job or did Patrick just decide to quit? And why they would choose Richard Karn to replace Patrick Duffy on Bingo America? Was Richard Karn hoping to be a Comeback Kid after being on Family Feud and he took a chance with this show?
