Repairing worn doorknob screw holes - GIF

I have the perfect solution - mine the fairways.

A bouncing Betty in every hole would lend a pleasant element of surprise too.

M. Klotz "......mine the fairways".
Me, have signs made. "Mind The Fairways"

Every hole? That subtracts, should be random. A real surprise would be cup 50' deep; "it's in there, I swear, a hole in one!"
And a 101' long pin?
Another one; a little machine that switches ball you tipped in with different stamp and number, "it's in there, I swear, a hole in one!"

I've seen that done with bamboo skewers, as a locksmith by trade for 40 years, I use brass inserts in the door with epoxy holding them after being threaded into the door.

Bamboo is way better than equally sized wood dowels. Shish kebab skewers and chop sticks easily gathered, and that long grain really holes screws well.
