PUNS! We know it's coming. The telltale signs are all there: the oddly specific setup, the unusual word choice, and, just visible out of the corner of our eye, the final panel of Stephan sitting at his desk awaiting the chastisement of one of his characters. Somehow the pun still manages to elicit a groan larger than we expected.   Fortunately for us--and for Stephan's job security--there are more than just puns in I Scream, You Scream, We All Scream Because Puns Suck. The entire Pearls Before Swine crew returns in some of the strip's most raucous cartoons yet. Rat tries his hand at public service as a judge and presidential candidate (he's accepting tips), Goat has a nasty run-in with Internet trolls (maybe it's time to get off social media), and Pig is dismayed to learn that there is no European city of "Hamsterdam" (much less a dam that holds back a river of hamsters). And like always, the Zebras can congratulate each other on a safe day and hope for a Croc-less tomorrow--in other words, the preys praise and pray.
