I created the teacher character based on Mr. Snell, a sub teacher at my high school who told jokes and drove around in his VW Bug with his dog in the front seat, wife in the back. He was definitely a fun high school memory! I tried to contact him last year to tell him about his character but he had since moved from the area so no luck.
Rest in peace, Mr. Snell. You made A LOT of kids laugh! :)
