I had one run over by a truck (Score 1)

It's true! My beloved HP-11c was run over by a big rig and it still worked!!! To turn it on ya just had to twist it a little. I used that calculator in for another couple years before it finally gave up the ghost. That calculator was awesome! I purchased a HP-41CV as a replacement and to this day it still does daily work. Gotta love the old HP calculators!
