Leonard Briggs is an older man who is studying business at Greendale Community College. He and Jeff have a comically antagonistic relationship and both take billiards for PE credit. Though noticeably older than the other students at Greendale, he acts in as reckless and laid-back a fashion as most young adults, often using slang and engaging in such activities as playing pranks and bass guitar and encountering "pregnancy scares".
