Johnny Ryan's compulsion to flout any and all accepted standards of decency in his humor and cartoons have not only garnered him a tremendous following - Instagram has banned him multiple times with hundreds of posts scrubbed from those accounts. (He can be found, currently, at @johnnyryanjohnnyryan1). From conventional gag cartoons to pieces decidedly unconventional and almost Dadaist in their humor, these are some of the most visually imaginative - and comedically brilliant - single-panel cartoons ever conceived, whether in the service of boner jokes or sheer visual absurdism.
