I recall a cartoon that was almost certainly made before I was born. Forties or Fifties, I think. It involved a couple of anthropomorphic animals – perhaps a cat and a mouse. (I’ll use those forms unless corrected.) The cat was trying to catch the mouse, and failing every time. He finally broke down and started feeling sorry for himself. He said something along the lines of ‘I’m nothing but an old used-to-was!’ The mouse took pity on him and tried to comfort him saying, ‘Aw, you ain’t no used-to-was!’
Does anyone remember this cartoon? What was it?
