Mr. Fritz is an English teacher at Pearl Bailey High School.
In "A League of His Own", Steve enters an essay contest to tell about their dads. His early draft of the essay meets with high praise from Mr Fritz who wants him to simply turn it in as it is. But when Stan criticizes it, Steve asks for more time to work on it and it is reluctantly granted. When evidence later points out that most of Stan's softball accomplishments are a lie, he loses interest in the project even though Mr Fritz Still wants him to just turn it in, but reluctantly grants him yet another extension.
Mr. Fritz appears at the Smith's leggings party in "Stretched Thin", along with his wife, Tonya Harding.
Mr Fritz is voiced by Jay Pharoah.
