Somebody solves Gretchen's complicated mathematical problem during recess who turns out to be Hank the janitor. Gretchen and Hank form a Math-letic club in the schools boiler room, much to the disinterest of the rest of the gang. Gretchen is disappointed that someone as smart as Hank is only a school janitor. The rest of the gang have a plan to try and find Hank a new job, by posting Hank's notes on the internet. Later on a university professor, the military and a scientist from NASA offer Hank a job. Hank declines all the offers stating he prefers math as just a hobby and not a job.
