every week or so Pastis does a strip where the punch line is a bad pun. the last panel will be one of the characters (usually Rat) insulting the author or threatening him with retaliation.
The gang over at Josh Fruhlinger’s Comics Curmudgeon blog* seems to be getting sick of the wordplay strips, but I love 'em. I’m an inveterate punner, and I’m impressed Pastis gets away with being beaten only by Rat, or occasionally Ringo Starr.
