Manliness and Remington

I'm pretty sure that all men, at least manly men, have in their heads an ever growing list of items and materials that fall into one of three categories:

1. You can punch this, no problems!
2. If you're angry, or you want to show off, you can punch this without breaking bones.
3. Receiving really bad news, when this is the only thing around to punch, is a recipe for knuckleular-disaster.

and leave it on the walkway.

my memory nears.

P.S. That's pronounced nuck-ole-ya-ler. (Kunckleular.)
