Absolutely Mind-Blowing!

A four-panel comic shows a man in a purple shirt and green cap holding a small pink flag with a peanut butter and jelly sandwich image. He asks 'WHAT'S THIS?' then sees another man in a yellow shirt waving a blue flag with a similar sandwich image and saying 'hello'. The first man then exclaims 'WOW FUCK THAT GUY' in shock. The setting is a simple indoor space with windows and a trash can.
