There was a recent thread on the alumni maillist about campus jobs. There are lots of funny stories about food service work (a perk for me was that I got first pick on steak night
and creative carpet cleaning. Other interesting jobs:
-tornado spotter
-painting yellow lines on roads and curbs
-"hostess" for theater productions with the task of ordering cookies from a bakery
-developing and printing images taken through the electron microscope
-College phone operator (a friend on evening shift got interesting information on liasons (eg, if there's a problem with... I'll be at this phone number)
-"Lightning Arrestor" involved turning off and unplugging all the physics department computers during thunderstorms.
-"Keeper of the Dome" involved prying the observatory domes free after snowstorms and hanging out the slit to scoop snow off from around the edges.
