You got it! It is from "The Life and Times of Archie and Mehitabel" by Don Marquis. It was originally written in 1927 by a newspaper reporter. Archie was a cockroach who climbed on his typewriter and jumped onto the keys one letter at a time and was not able to use the shift key to punctuate or capitalize. Mehitabel was his friend, an alley cat whose theme song was "Wot the hell,wot the hell, tojours gai, tohours gai! There is life in the old gal yet!"
Very few people I have ever run into are familiar with Archie and Mehitabel and they are two of my favorite characters of all time. I come from a family of bookworms with very wide ranging tastes in reading material. LOL!
