|Professor Bublitz is a professor of Botany at Greendale Community College and a major Dave Mathews band fan. He was at one time considered a suspect in a series of unfortunate pranks being pulled on unsuspecting students on campus. An unsanctioned investigation into Bublitz both proved his innocence and his guilt. Professor Bublitz first appearance was in the Season Five episode "Basic Intergluteal Numismatics". He is portrayed by musician Ben Folds.|
In the study groups fifth year at Greendale, a serial prankster who dropped quarters into students butt cracks resurfaced and began terrorizing the campus once again. Professor Bublitz was suspected of being this "Ass Crack Bandit" due to his love of the Dave Mathews band. Jeff and Annie had launched an investigation into the matter feeling that the official school sanctioned one was looking at the wrong suspects. Annie believed it was a member of the faculty and Jeff noted that many of the taunting notes the Bandit left behind resembled Dave Mathews band lyrics. After searching the Greendale database, Bublitz name popped up along with seven other teachers. They split up and crossed a few suspects off the list before meeting up outside the schools hydroponics lab. After comparing notes they went into the lab to confront Bublitz.
Slightly agitated by their appearance , Bublitz stopped watering his plants and asked if he could help them. Annie told him they wanted to ask him a few questions which elicited a muted response from a scared Bublitz who then quickly ran away. Jeff and Annie pursued him through the dense maze of flora in the lab knocking over various plants and shelving units. They briefly lost sight of Bublitz until Annie spotted him running towards the back. She pushed over a shelf in order to reach him ending the chase. Finally cornered, Bublitz was found to be holding what appeared to be a potted Marijuana plant. He told them that if they were going to confiscate it they should know one thing: "It's a mild, kind sativa, perfect for playing guitar." Although guilty of growing pot in his lab, Bublitz was cleared of being the "Ass Crack Bandit" when Dean Pelton ran into the lab to let Jeff and Annie know the bandit claimed another victim ("Basic Intergluteal Numismatics").
