this is a geeky joke that only network administrators will truly appreciate:

How to not stay lost: always carry a small shovel and loop of fiberoptic cable. If lost, bury fiber optic cable in the ground. When the backhoe arrives within the hour, hitch a ride into town.

(for those who don't get it, it seems that in the same way mobile homes cause tornados to come down upon then, fiber-optic cables cause backhoes to dig through them. anyone who'd in IT will tell you of the day of the fiber cut.)
