The ribbed tumbler is not the most forgiving medium and that glossy surface is a bit tricky. We were at a wonderful cookout celebrating the confirmation of two teenagers. I noticed that people had signed their cups so they could reuse them. I got so preoccupied thinking about finding the sharpie and drawing on my empty outside full inside tumbler that I might have tuned out some the conversation around me. Later I looked at this face and thought "hmmmm looks a bit like Woodrow Wilson hopped up on caffeine".
