I'm not sure where you got your data about cast members, but someone needs to check it with NBC. Dave Garroway, the original host of Today, appeared on at least 2000 episodes during the first nine years of the run -- 5 days a week for at least 48 weeks a year for nine years -- but you credited him with 3 episodes. Jack Lesculie was an everyday regular on the show for at least 3 years in the beginning. To credit these men with fewer appearances than J. Fred Muggs, a chimpanzee who appeared on the show during that era, is an insult to their memory -- particularly since Muggs was biting them all the time! In those days, the program was live, so the human performers had to be careful how they reacted. Seriously, this was one of the most important programs in the early days of television, thanks largely to the work of Garroway, Pat Weaver and newscaster Frank Blair. It trained people to get up in the mornings and turn on their sets -- a habit we've continued to practice for more than half a century!
