Uncles and dad built grandad a new one circa 1977. Two seater. They had 9 kids and 35+/- grandkids so made sense. Uncle sat down. Other uncle traced his ass. Old man made one beautiful cut with a chain saw. Grandad went in to try it out, stormed out 10 seconds later. Came marching back from his wood shop with a 24" long bastard file and proceeded to smooth it out after getting the splinters out of his ass.
Never forget when they installed a bathroom around 1980. Grandad was pissed! Said "even my cows knows not to [bleep] where they sleep!".
