My neighbour did this a couple weeks ago. He has a literal flamethrower and burned the weeds that are in the little cracks on the sidewalk. (fyi, he has a fire extinguisher, so if it started catching on fire, he could put it out.)
Where are the good and original roasts you used to make? Did you forget how to be creative? Then again you have a brain the size of the head of a pin surrounded by a massive brain tumor!
