Do you enjoy watching the desperately puzzled faces of your co-workers day in and day out? Then we are sure you’ll enjoy being the source of their frustrations as you stride down the fluorescent hallways with this fine koan of a t-shirt…

High quality heavyweight black tshirt with the phrase “There are only 10 types of people in the world: Those who understand binary, and those who don’t” written front and center in white ink. If you don’t get it, you just shouldn’t get it now should you? ;)
