How did Jon Hall come to be nicknamed Maddog?

Answer 1

I lost my temper at my Dean of Instruction where I was teaching, not my students. The ensuing argument was "Too hot for mad dogs and Englishmen". The Dean was British, I was the "mad dog".

Answer 2

Jon Hall received the nickname maddog when he was in college by his students. The students named him maddog because he couldn't control his temper very well at that time.
