A substitute teacher in Oklahoma is looking for another job after using questionable judgment with some geometry questions.

One mom says she looked over her son's homework and found references to serial killer Ted Bundy and someone called Creepy John , who watched neighbors with a telescope.

The Bundy question asks how far up Ted Bundy's ladder reaches.

Parent Christina Mattalianio says, The first thing that popped into my mind was just, 'It's creepy,'... I don't know if he's trying to be humorous or... if maybe that's some of his personal interests.

The substitute says he was trying to engage the students by getting their attention.
