In the wide spectrum of cartoons as humorous drawings, which include single panel (gag) cartoons, strip cartoons, moving pictures etc, Patrick has concentrated on British joke cartoons. Although they have a place in the pantheon of humour, Patrick has avoided political and satirical subjects. His humour is gentle and often replies on "bad puns and much more." Anita O'Brian, the Director/Curator of the Cartoon Museum has described his work as "a great sense of humour." Patrick's recommendation is that "every loo should have a copy!"
