I have seen quite a few. There are a couple that come to mind. We had this one guy in our league, he was a pretty big dude. He would take three steps forward putting his ball in motion,...and then go rotate his arm/ball up and completely over his head and down, then chuck the ball around 22 mph. Not very accurate, but a lot of collateral damage. We called him the "windmill".LOL.
Then we currently have this guy who sets up on the approach,.....and stands there motionless, literally 35-40 seconds,.we timed him. You want to check his pulse because he don't move at all. If you are bowling next to him you almost have time to go get a sandwich, or have a smoke, visit the restroom whatever before, you can bowl. Its pretty funny, and annoying at the same time.
