There once was a lonely little pig that constantly followed Spiderman, always nuzzling his leg and oinking tenderly. Spiderman finally caved in and decided to keep the little pig under one condition: the pig was to take a broom and sweep up all of Spiderman's leftover threads after having fought crime. The pig felt such affinity for Spiderman, he happily accepted—and did a good job too.
