And now for afunny story, unrelated to trailer hitches.
Way back in my youth, I was a young turd Wrangler.
From time to time, I had to operate an antiquated cab over vacuum truck. Now back then, the doors didn't have fancy curved lines, they had nasty sharp corners.
I had pulled up to a tank to clean it out. I had pulled up close to the water meter box to hook up a water hose at the same time. I had my hard hat on, but this was before the fancy adjustment knobs were available on the hat band. It's July in the coastal plains of North Carolina. I was sweating so bad my hat band was slick.
Got out of the truck, leaving the door open. Bent down to hook up the hose, hat slipped off, hooked up the hose, picked up my hat and stood up fast.
I drove my head into the bottom corner of that door.
Now it wasn't too painful but I knew I saw stars. When I finally got my wits, I went to wipe the sweat off my face and forehead.....wasn't sweat.
Got 5 stitches, and wrote up for not wearing my hard hat.
