Scraping rust off the high ceiling of a painting and anodizing factory and then spray painting it. I had to start at 11 pm and be out by 7, when the first shift started. It was a summer job and it was usually warm and humid. I was drenched and filthy every morning and had to spend time standing in a box on a forklift. It certainly paid well, but it was the hardest and loneliest job I ever had.
