15. The UroClub

This last invention on our list is on here for how audacious it is. This invention is certainly a niche item. The UroClub is no ordinary tool for golfing, it’s not even used to golf with. Like the name hints at, it’s a club you physically urinate in when you aren’t able to run to the bathroom in the middle of a game on the green.

The club has a hollow cavity that can be opened and peed into behind a privacy cloth. Hopefully anyone who buys and uses the club doesn’t forget they did, leaving it to mellow in their bag with the rest of their clubs.
