Leavelle is a professional bodyguard trainer who owns and operates Leavelle's Bodyguard Academy. Judging by his accent, he seems to be from Texas. At the Bodyguard Academy, Leavelle's teaching style is based on constantly berating the cadets, as seen when Homer took the training course. In the end, Leavelle let them pass, and rewarded the entire graduating class by singing for them an impromptu rendition of "I Will Always Love You", the theme song from The Bodyguard. However, he sang it so badly that the students all left, apparently interpreting the song as an indication that it was time for them to go.
