In this comic by Roz Chast really sums it up nicely, for grandmas, parents and, let's be honest, sometimes even ourselves during our darkest moments of troubleshooting.
It reminds me of a funny story that happened to my wife's grandma a few years back. Her television was hit by a power surge and began speaking Spanish (picking up some AM radio station probably)...even when unplugged. She later joked that the voices, temporarily muffled under a blanket, were laughing at her. We convinced her that she'd just hit the wrong button. OK, OK, we didn't. We're not that cruel. [bookofjoe]
