Remember figuring out how easy it is to punch holes in walls, because walls are just sheet rock?
Except for the part that's a 2x4?
Ouch! ouch ouch ouch!!!
I knew a rooming-house superintendant who got tired of replacing the same punched-in piece of drywall.
He drove nails into the drywall from the back, just shy of the front paper. It only got punched in once after that.
