My coworkers are lamenting that I will be leaving at the end of July to go back to school and are (jokingly) trying to convince me that I want to stay. Here is an excerpt from my coworker's email to me the other day:

Those who cant,

Teach

Those who cant teach teach Gym

Those who cant teach Gym spend endless hours explaining esoteric mathematical theorems to people who in the end are really only pretending to understand and are actually thinking about what they are going to have for dinner.
