Earth 33 1/3 is the world on which the various cartoon characters created by Tim Quinn and Dicky Howett in various Marvel UK titles of the early eighties exist. Apart from Earth 33 1/3 itself, the most successful strips connected with the place were Jet Lagg, Hulk the Menace and The Fantastic 400. The long running Doctor Who? strip (a spoof of Doctor Who) may also have been set on Earth 33 1/3. Other strips by Quinn and Howett during the same period included The Fairly Amazing Spider-Hound, Bullpen Bedlam, Flickers and Whacker's World as well as the multi-part serial I Was Adolf's Double.
