My friend Tim is a comic artist and we frequently spend time drawing together. Occasionally we will prank each other. Tim likes to draw inappropes naked pictures in my sketchbook and I retaliate by drawing angsty-teen-girl unicorn drawings in his.
On one particular day back in 2005ish Tim decided to combine the two and drew Prince Heartfire, Protector of All That Is Good - a naked, erect male unicorn-person. (the counterpart I drew in Tim's sketchbooks is Princess Ravenwood, a busty, full lipped unicorn princess)
So imagine my surprise when I stumbled onto a drawing that was virtually identical in posture, line, and freaking bizarre content as Tim's original drawing.
