Image description: A crude drawing of a stick man sitting in a chair in an unusual position. Right leg is bent at the knee with the sole of the foot flat on the seat and the knee up towards the chin. The left leg is bent at the knee where the lower leg is flat against the seat and the foot is on the seat under the buttocks.
