I remember this show with a lot of fondness, and yes, nobody believed me either this show existed. I remember getting up really early in the morning to see this show with my brother on our rinky dink black and white TV set. We also used to watch Whitney and the Robot. I have not looked it up yet, but this show is almost an impossibility to find anywhere, and there are a lot of off the wall things on the Internet.
At any rate, this show was a lot of fun to watch, and we would see things about like eating your vegetables, being nice to others, and other things that were "cat". One line I will never forget is: "Eat your vegetables!" and here is Me crinkling the chocolate wrapper with his friend saying "No candy!"
Of course, there was the segment of grandpa giving his nuggets of wisdom at the end of every show, and you would his granddaughter say in a "hall" reverb effect in the background, "Oh, grandpa!"
Oh yes, and I clearly remember "Can you find Me in this picture?" and they would show some painting and Me's face would flash on the screen. my brother and I would look and look for it and we would be so proud when we spotted Me's face.
