This is right up your alley. Forget about the CNC sign making - make
human body parts!
I can just imagine the conversations...
"Gawd-DAMMIT! Who didn't replace the nipple cartridge in the
printer?! Johnny, were you messing in here with your friends again?
We already went over this - it's _not_
funny to attach body parts to
your friends when they're sleeping. I swear one day I'm going to put
a lock on the damn thing."
