Some time in the middle of the 1950s, I remember seeing a cartoon on Saturday morning kids television in New York. It's been a while, now and my memories of it are fading (along with many other memories) but the plot was of a war between the 'happy' people and the 'sad' people.

The sad people sang:
"We're happy when we're sad, ugh!
We're always feeling bad, ugh!"
"How are you?"
"Terrible!"
"That's fine!"
"We're happy when we're sad. ugh!"

Does anyone else remember it?
