You don't have to be a rocket scientist to create cartoons, but Pat Byrnes erred on the side of caution, getting his aerospace degree at Notre Dame in 1981. His science skills have languished, however, as he has spent most of the last 25 years following his love of writing, acting, and cartooning--and most recently as a stay-at-home dad. Since 1998 he's been a regular contributor to the New Yorker.
