Re: Mask required...Child Mutilating Nazi's...
I never used a knife to de-cajone anything but I've used the "rubber bands" quite a bit back when my sister had a decent sized herd of bovines and pigs.
They always called me when some critter or the other had to be dispatched.
Started calling myself...Dr. Death.
When I had to use the bands...I was Dr. Death and his deadly de-nutting doughnuts. 😃
