"Good" probably meant beefy looking Master. Funny as a lock picker because Master are famously easy to pick and for some reason the beefier the lock body the easier they are to pick.
The master paradox is so extreme that one of the more famously difficult Master locks has a plastic body.
It's just funny to seriously think about locks when it's easier to e.g. remove hinges then deal with the locks.
Physical security is a very deep rabbit hole. Why bother with hinges at all when I can bypass both of those locks faster than I can put in the combo.
Counterintuitive too like how smart convertible owners don't lock the car. Easier to replace whatever they wanted to steal than whatever they wanted to steal and your top.
