Thanks to all who replied.
Most have not had any problems doing this (some for many years, many times)
but a few have blown a $2.00 fuse. Some said blowing a CPU is possible
(but think the hardware support folks were jumping the gun) but no one has
actually blown a CPU doing this.
Thanks again to everyone around the world:
