Have you ever stepped in dog poo and not realized it? You're walking around, or sit down somewhere and get a whiff of something. It smells like poo. That's when everyone starts checking their shoes. The worst part is when you actually find something mushed into the intricate pattern on the bottom of your shoe.
This t-shirt attempts to sum up that experience with a simple question. I'm not sure how many people will find it funny, or possibly even understand the joke, but I'm sure there are some who can relate.
