the underwear drawer

his street name is TI-85

I was walking down the stairs in the hospital today when I saw the nerdiest graffiti ever. OK, so you know how the floors in a fire escape are labeled? A "6" indicating that you're on the 6th floor, a "7" indicating the 7th, etcetera? Well, on the 5th floor landing, there was a "5" painted on the wall. And also jotted on the wall, in black ballpoint pen, was a square root symbol around the 5, an equals sign, and next to that, "2.236"

Oh, graffito-tagger. You may work in the hospital now, but you haven't lost your edge. You are like a young Keith Haring. With math.
