Peter Parker (aka Spiderman) is taking geometry in high school and, surprisingly, has a lot of trouble with it, especially when it comes to circles.

He asks his girlfriend, Mary Jane, for help figuring out the circumference of a circle. Mary Jane tries explaining it a few different ways, but he still doesn’t get it. She tries one last time:

“Imagine that you have a group of villains surrounding you. You jump up, swing around and wrap them with a single strand of web. The length of that single strand of web that you use to wrap the villains would be the ‘circumference.’”

Spiderman gives her a blank stare, “but I still don’t know how to find the length of the web, this circumference?”

Exasperated, Mary Jane, “we went over this many times, don’t you remember it, Spidey?”
