I don't see students here. I see seamen. I didn't create them, but once you climbed aboard, I saw seamen inside of you. More importantly, you stopped giggling at the word seamen.
— Admiral Slaughter
Admiral Slaughter is the boating professor at Greendale. He is a war veteran and once was a machine gunner on the U.S.S. Denver during WWII. Slaughter lost his savings in a Nigerian scam and was forced to teach courses at Greendale for extra money. A tough but fair instructor, he takes a less traditional approach when teaching his students. He prefers that they learn as they go and simply corrects them when they are wrong or praises them when they've done something right. His first and so far only appearance was in the Season One episode "Beginner Pottery". He is portrayed by veteran actor Lee Majors.
In the study group's first year at Greendale, Pierce decided to take a boating course for the spring semester. After asking the study group if they were interested in taking the course with him, Shirley, Britta and Troy enrolled as well. Star-Burns had signed up as well and they all went to the campus parking lot for class. It was to be held on an actual sail boat, the S.S.Nose Candy, and once on board they were greeted by the teacher Lee Slaughter. He explains to the class that they will be graded as a group. How well they work as a team and follow orders will determine whether they all pass or fail. Shirley catches his attention with her enthusiasm and he immediately promotes her to "captain" and leader of the "crew" much to Pierce's annoyance.
