Sometimes FCC filings can be hilarious.

FCC Outage Report 99-149
July 30, 1999, Lamesa, TX

A contractor was providing backhoe training to his employees on his
property in Lamesa, TX.  The contractor told his employees that no
utilities existed in the practice area and instructed them to exercise
their backhoe skills.  The employees began digging and subsequently
severed an AT&T cable that crossed the contractor's property.  There
was no One-Call notification to AT&T, however there were marker poles
posted on the property and were clearly visible.
