In 1975 a prime-time animated TV special called “Be My Valentine, Charlie Brown” aired on the CBS network. At the school which Charlie Brown attends, a box labeled “VALENTINES FOR THOSE WE LOVE” is placed in his classroom. Charlie Brown brings a briefcase, hoping he will get lots of valentines, but after all the cards are passed out it turns out he gets none except for a very small candy heart reading “Forget It Kid.”
