Lots of summer still remaining folks. Is a sprinkler grill #1 on your project list?
GIF and short perfectly-subtitled video below. Appears to be a group of Norwegian gentlemen? With either a fireman or a man dressed as a fireman, working the propane tank.
Like many absurd DIY projects, this one contains some gems. First of all, one of the guys notes the legitimate culinary advantage of such a crazy setup - the angled flame delivery of the sprinkler addresses the age old problem of sausages or hot dogs being unevenly browned on the "sides", even with a perfect flip. More importantly, is that a giant red warning triangle painted on the side of their house? For aircraft? Or simply a warning to sane people to stay away?
