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.
LOL...every time I see a 55 gallon drum I think of Jeffery Dahmer...(shudder). Unfortunately where I work, they are stacked by the pallet loads!
