Be Up to Date (the final episode of the third season of Cheyenne that aired on July 1, 1958) In the 1938 Betty Boop cartoon of the same name from Fleischer Studios, Mae Questel bid adieu to voicing Betty with this less than hilarious short which finds Ms. Boop taking a mobile dry goods store to some yokels up in the hills. It's notable that Betty's look has continued to evolve, perhaps slightly but still noticeably. But in the 1958 episode, Clint Walker reprises the role to voicing Cheyenne Bodie. See more
