Per Stormin Mormon:
At 75, he'd also had a
section of his colon removed and for whatever reason,
the old fellow had the most epic farts I'd ever heard
in my life. I swear, when he'd go to the bathroom,
he'd let out farts that lasted 15 seconds without
pause. His farts were breathtaking.(???)

This guy might have had him beat:
