When I was a young "hippie" in the late 60's, early 70's, there was an underground comic written by Gilbert Sheldon called "The Fabulous Furry Freak Brothers. Phineas Freakears was one of the characters, along with Fat Freddy and Freewheelin' Franklin. And a cat that had no name, it was just called Fat Freddy's cat. I also use Freewheelin as a user name in some forums.
