On a Monday morning (mid-70's), my boss told me to call the phone company to repair a phone in an office upstairs from his. Knowing they'd want details, I asked him what was wrong (pre-modular phones, direct wiring to the wall). He was reluctant to tell me, but finally I got the story from him. He had been working on Saturday, trying to meet a deadline for complex financial statements, and the phone upstairs kept ringing and ringing. It was loud and intrusive and interrupting his concentration. After 3 or 4 trips upstairs to answer it (no one there, of course), he was so frustrated that he took a pair of scissors and cut the cord! At least he was able to finish his task without further interruption.
I asked him why he didn't just take that phone off the hook and lay it on the desk. His startled look and growl of frustration made me laugh all the way to my office to call the phone company.
