Cool Shirts Guy is a dentistry stock photo and a copypasta posted with it. It is notable for being massively spammed in dedicated threads, along with it being a response to any post requesting a meme. The copypasta explains how the meme was made in 11 years, and is apparently the "ultimate meme". More than half of the copypasta is dedicated to the poster complimenting themselves. He can also be found on the greg.com website as their place holder photo.
