Thank God no...but we would get "off the wall" brands of chippers that we so rigged and had safety features bypassed that it's almost amazing accidents don't happen more often.
In college (this was pre-caller-ID), my friends and I would prank call chemical or other supply companies:
"You have big drums of sulphuric acid? How strong? How much does it weigh? Can I fit it in a truck? Will it disolve a body, er a big dog? Even fillings? Yeah, the dog had fillings."
Etc.
