Idioms

I'm trying to track down an animated short which I saw on TV one saturday morning in the 80's. The entire short was filled with idioms, including "It was raining cats and dogs," "She was staring daggers at me," and "I died laughing". The main character, a hard-boiled detective type, speaks the previous in voiceover, and the idioms are illustrated literally as he does so. So when he says "It was raining cats and dogs," cats and dogs are falling from the sky, etc. The style was thin black outlines on a white background, probably colored in with something like watercolor. It was a funny toon, and I remember it though I only saw it once. I wish I could find it somewhere.
