In the cartoon The Flintstones, (which ran from 1960 to 1966), the name of Fred and Barney’s lodge is The Loyal Order of Water Buffaloes, Lodge No. 26.
What Is The Loyal Order of Water Buffaloes? The Loyal Order of Water Buffaloes is a fictional society, similar to the Freemasons Lodge, which holds regular meetings, tournaments and contests for its members.
The lodge is similar to a guild or fraternity, and only men are allowed to become members.
In early episodes of The Flintstones, the lodge was actually called The Loyal Order of Dinosaurs. The leader of the lodge is called the Grand Poobah - a position that Fred is elected to in one episode.
