My longest was 7 hours of lining from the side of my butt to almost the side of my knee. I think I saw God. I had the shakes really bad after and by the time I got home, I had a fever. I called my mom when I was done like I usually do to let her know the damage had been done, and I distinctly remember telling her I was never getting another one...that was a couple tattoos ago, of course.
