Leavelle

Leavelle is a professional bodyguard trainer who owns and operates Leavelle's Bodyguard Academy. Judging by his accent, he seems to be from Texas.

History
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.

Behind the Laughter

 * Leavelle's design is based on Texan detective, as he appeared when escorting when Oswald was shot by . Leavelle trains the bodyguards by pretending to shoot their protectee from a grassy knoll on a cart. This is a reference to the grassy knoll at the site of President John F. Kennedy's , Dealey Plaza and a scene from the Kennedy assassination film Executive Action (1973).
 * In the DVD commentary for the episode, Mark Hamill admitted that he really enjoyed doing the voice of Leavelle; voicing himself, not so much.
