I saw a movie in the early 70s, the film itself may be early 70s or late 60s. The movie starts with a kid waking up by an alarm clock (that he invented?) which pulls a string attached to his toe to wake him up. He excitedly goes down to the kitchen and has a piece of cake for breakfast (it may or may not be his birthday). Then he happily runs off to do whatever he’s going to do…
That’s all I remember from the whole movie.
PLEASE HELP! Does anyone know?
