cool things with wheels since 2006
Son of a... troll level hard! :D
When I was at Loring AFB some crew chief's wrapped a gallon can of waste 5606 hydraulic fluid (think Dextron II) in rags and buried in a snowbank. The poor Maine potato farmer who was running one of the big Oshkosh rotary snow plows about had a heart attack when he saw a stream of blood red snow and bits of flannel shirt flying out of the chute of his snow blower.
Whoa... that's just wrong. Fake death is pretty harsh for a prank, on the random stranger, even worse
