Hi everyone,

I've been bummed out with dogs this week, so I've only been partially
reading the mail.

But, I felt obliged to chime in. Back in the late 70's, I was just starting
out; working for someone else, and left a flashlight in a TV. I had it
jammed in around the yoke, to illuminate the tuner cluster (I think).

Fast forward to the mid 80's, I had my own business, and got called out to
service the set. When I took the back off, there was my flashlight, with the
switch on, and, of course, dead batteries.

The customer, & I both got a good laugh out  of it.
