There is nothing else to say on this subject. Dave looks down from his place above ten pin bowling alleys everywhere and decides on the outcome of an individual ball.
There are times when you think a ball is a sure fire strike but Dave thinks differently and leaves the two end pins upright. It is impossible to then knock over both pins with the second ball unless your name is Fred Flintstone.
If Dave doesn’t like you your balls are destined for the gutter that runs alongside the very slippery main bit that you’re meant to roll them down.
It is possible to partly defy Dave by using the rails that stop the ball from going off the main slippery bit. However this does come at a price as people that use the rails are considered to be real woosses unless they are under the age of five.
Dave is never very impressed if you score less than a hundred although quite frankly who cares. Anyone who is good at ten pin bowling has to be in need of a life and probably has all the gear including a special bag for their own bowling ball and a tailored bowling shirt.
Dave can shove off.
