Parker is on the left because Spider-Man could build a web in there and Wilber because when I get hands on that rack all I could say is "what a hog" (Charlotte's Web).
I'm terrible at jokes haha. I was pulling your leg. When I read your topic I assumed there would be 3 bucks, Peter, Parker, and Wilber. When I read your actual explanation I realized there was only 2 bucks.
