I didn't know that there were adults out there who played wiffleball, let alone adults who took their wiffling so seriously.
YouTuber Wiffleboy28 has a whole channel dedicated to grown men playing wiffleball. His latest video is particularly impressive. Throwing a wiffleball with any sort of force is a challenge. Wiffleballs aren't meant to fly like this, and yet these guys are really chucking these things.
Check out how hard these guys are throwing these things. I'm legitimately impressed.
