Golf
Golf is a ridiculous sport, and no matter how many people watch or play it, its a lonely man's game. The only competition is yourself - it's not like the players actually interact with each other. No, that would too interesting.
Instead, golf showcases silly men with too much time on their hands who dress like 1920s teddy bears to hit a tiny ball into a tiny hole hundreds of yards away, in complete silence. The only worthwhile spawn of golf is 'Caddyshack'.
