The art teacher is a one-shot character who appears in the episode "Riley Wuz Here". His character is based on a famous American painter, Bob Ross. He allegedly served in the U.S. military during the Gulf War. He is portrayed as a soft spoken, compassionate man who desires to help Riley improve as an artist. He first meets Riley after Riley spray paints "Riley Wuz Here" on the side of a house. He critiques the mural and helps Riley make it smaller so that the message is clearer.
