back when we used pagers at the power company a coworker lost his pager, we thought it was in the ditch where we were last working.... so we called it to see if we could find it in the ditch.
about 2 days later i took the truck the guy normally drives out on a trouble call. i was getting ready to leave the garage and hear this weird buzzing coming from under the seat. thought something was wrong with the truck. i mentioned it to my coworker and he said Yeah i've been hearing that too. upon closer inspection we found the lost pager buzzing around on the floor... it was set on vibrate!
you call them ferrets, i call them weasels.
