You have questions. I have some answers.
Q: I vaguely recall a show called "Happy" about a baby whose thoughts were heard by viewers, sort of like Cleo on "The People's Choice." Am I dreaming?
A: You are not dreaming. “Happy” aired on NBC for a single season in 1960-61. Ronnie Burns and Yvonne Lime played a young couple running a motel and dealing with their infant son Happy (played by twins David and Steven Born). Happy’s observations were shown “through facial expressions and an off-screen voice,” says “The Complete Directory to Prime Time Network and Cable TV Shows.” This, as you noted, was similar to the device used on “The People’s Choice” (1955-58, NBC), where the basset hound Cleo was commenting.
