Before getting his big break, Dooley worked for a number of years illustrating hog oilers for Cudworth-Hooper's successful line of agricultural and industrial equipment. While not exactly a comedy training ground (though 'hog oiler' sounds like a pretty hilarious piece of equipment), working for Cudworth-Hooper allowed Dooley to hone his drafting skills and keep working with his drawing tools.
After getting his big break to create the comic strip Frank and His Friend, Dooley was quoted as saying that he would never buy any Cudworth-Hooper appliances for the family home. "Not once I've seen how they're made," he said.
