is the substitute fourth-grade science teacher at Wagstaff School who covers for Mr. Blevins in the episode "Topsy." He makes his first and only appearance in this episode.
He is voiced by Mark Proksch.
== Profile ==
=== Appearance ===
He has slicked-back dirty blond hair, but what's most interesting about his appearance is how he dresses. Unlike everyone else at Wagstaff—even the teachers—he's dressed for a formal occasion. He's assumably wearing a Thomas Edison costume.
=== Personality ===
He is a big fan of Thomas Edison, to the point of having an unhealthy obsession. Despite being an Edison expert, he hates the negative aspects of him, such as his electrocution of animals. He disapproves of volcanoes as science projects, and he subsequently develops an antagonistic relationship with Louise. He even went as far as to destroy her paper machete volcano out of anger and frustration ("Topsy").
He is openly insulting and mean, calling a child a "moron" ("Topsy").
