Basketball was invented by James Naismith. He wasn't Jewish.
No one knows for sure who invented baseball. (No, it wasn't Abner Doubleday.) Whoever it was, we're pretty sure he wasn't Jewish.
Before we start rattling off every sport that wasn't invented by Jews, let's get to the one that definitely was: ultimate. (Don't call it ultimate frisbee.)
For those who haven't frequented college campuses in the last few decades, ultimate is a crossbreed of frisbee and football. Alright, calling it a real sport is somewhat of a stretch, but it does have a world governing body and everything.
So who is the Jew behind ultimate? Joel Silver, who co-created it during his time at Lafayette College. If that name sounds familiar, it's because Silver grew up to be one of the most powerful producers in Hollywood... and a man so large that is seems improbable he ever played a sport in the first place.
Another sport invented by Jews?
Competitive arguing. But that goes without saying...
