When you hear the words "chainsaw" and "prank" in the same sentence, you know it's either because it's awesome or something went terribly wrong.

In this case, it was all awesome.

These two buddies were traveling through Norway and Sweden when one of them got some shuteye at a rest stop. That's when his pal came up with this ingenious joke by starting a chainsaw and putting it against his neck. And, relax, everyone -- there was no blade.

Of course, the poor guy who thinks he's the latest victim in a real-life Texas Chainsaw Massacre movie doesn't know that, which explains why his eyes dilate like he just did a speedball.
