At home, he has a special someone who keeps him in check - his wife of 45 years, Christine!
The happy couple renewed their vows for their 43rd anniversary, and Si surprised her with a special song as she walked down the aisle. The song, titled "Can't Take The Swamp Outta The Man", features Kix Brooks on the recording.
Brooks is one-half of Christine's favorite country group, Brooks & Dunn, and helps Si sing about his love for her.
"There just ain't no 'mount of money," croons Brooks and Si sings back, "That can change me and my smoking hot honey."
"Can't Take The Swamp Outta The Man" is included on an EP Si released on iTunes in 2014 called Me and My Smokin' Hot Honey.
Si and Christine were married in 1971 and have had two children together. They also have eight grandsons!
While she has chosen not to participate in the filming of Duck Dynasty, they have been happily married for 45 years.
