That's Phil and Rex, and no, they are not brothers. If a panel cartoon is good enough, it can wind up adorning kitchen refrigerators, office bulletin boards, and social media feeds for years on end. So how do panel cartoonists do it, with artwork that can sometimes amount to no more than a few scrawled lines, and text that might comprise just a few words? It’s a question that, apparently, haunted Phil Witte and Rex Hesner — so much so that they wrote a book about it, “ Funny Stuff: How Great Cartoonists Make Great Cartoons .” Well, the impetus was actually a little more complicated than that, as you'll hear when we sit down with Phil and Rex for the latest episode of "Strip Search." Also, find out the latest about the rollout of the latest "Pet Peeves" collection by London & Chianca, " Nerd Dad! " A caption-less cartoon by "Funny Stuff" co-author Phil Witte.
