I spent Christmas at my brothers in northern California, and we came up with this gag together when we were joking around. The best humor comes when two similar minds start bouncing ideas back and forth, which is by far the most enjoyable way to create gags.
Basically, we were discussing the way two jock captains would pick teams for a sport in school, and the unfairness of the whole process. There would always be the nerdy guys left at the end which someone had to pick, and the groans and moans that would come up when one of these guys was finally chosen. Just completely unfair and cruel. So, in my fantasy world, the science geeks rule, and the jocks must suffer. heh heh..
