O' Gill's Dental Floss Farm is a farming business. It is run by Farmer O' Gill and his farm workers. They are best known for growing the best dental floss in the land.
Some of their flavored floss are original, cinnamon, and mint. It only appeared in The Wonderful Wizard of Ha's.
- Phil Vischer states in the commentary that this was inspired by Frank Zappa's "Montana".
