At first I thought this was going to be a welder doing fancy moves with his torch, then...

Sort of like backwards Major Kong

Man, that's a cutting torch.

Sort of like you sawing off the part of the board you're sitting on.

Pipe did not like it very much

This would've been heeelarious if it starred Jim Varney.

Pipeliners are the cowboys of the welding world, and for good reason.

I've had similar things happen on a smaller scale when cutting two tacked up headers, granted when the tack broke it only smacked the grinder out of my hand... fucking crazy bastard is lucky, torch assemblies/hoses aren't meant to be yanked around like that.
