I find it hard to appreciate the widespread interest in comic books or in so-called "graphic novels". Clad in various colors of spandex, each with his/her own mental health problems and traveling from world to world on this or that mission, their images inexplicably keep bringing adoring fans/readers to conventions and comic book stores.
I might like to propose a superhero more in keeping with everyday life:
Faster than a speeding shopping cart. More powerful than a soda can recycler. Able to leap over long checkout lines in a single bound. Look! Up in the shelves. It's a chicken. It's a steak. It's Souperman! Yes, it's Souperman - strange visitor from the Planet Coupon who came to earth with powers and abilities far beyond those of mortal shoppers. Souperman - who can change the course of mighty floor sweepers, bend cash register receipts in his bare hands, and who disguised as Can Dent, mild mannered stock clerk for a great metropolitan grocery chain, fights a never ending battle for fruits, juices and Honest Weight.
