Coach Bogner is the physical education director at Greendale Community College. He insists that his students wear the required P.E. uniform for all his classes, even billiards. His first and so far only appearance was in the Season One episode "Physical Education". He was portrayed by actor Blake Clark.
Jeff signs up for Billiards class because he considers it the only sport you can play while looking cool. Coach Bogner sees him playing before class and compliments his obvious skill at the game. Bogner then hands out the standard issue attire for PE classes at Greendale which consists of a tee shirt and a pair of rather small athletic shorts. Jeff's height and long legs contrasted with the high-sitting shorts make him self-conscious (his insistence on wearing his leather jacket doesn't help) and unable to play well. He asks if shorts are really required but Bogner insists on maintaining the dress code. Bogner also detects that Jeff is more worried about looking cool than playing pool and shames him in front of the class for his vanity.
After some inspiration from Abed (and a few insulting PA announcements from Bogner) Jeff dons his shorts and challenges Bogner to a game of pool. Bogner accepts and both players perform well. After a few shots, Bogner accuses Jeff of not learning anything, just how to look cool in shorts. Jeff counters by pulling his own shorts down exposing his underwear. Bogner follows suit and they continue playing wearing only their briefs. As the game comes down to the last shot Bogner again confronts Jeff, saying that no matter who wins, all that would be remembered is that one man "loved clothes and the other loved game." With a cry, both men rip off their last piece of clothing and stand naked before the crowd. Bogner misses a tough rail shot on the 8-ball but Jeff sinks it on a long corner shot to win. Coach Bogner congratulates Jeff and gives him permission to wear whatever he wants during Billiards class. Having finally earned Bogner's respect, Jeff announces that he chooses shorts. Bogner responds by kissing Jeff full on the mouth much to the shock of the crowd.
