Schlock: I'm sort of like a special forces guy. My squad does the behind-enemy-lines stuff.
Jevee Ceeta: And what kind of 'stuff' might that be, exactly?
Schlock: Oh, you know. Stuff. Sneaking around, blowing things up, running away.
Schlock: Mostly it involves running and getting dirty.
Jevee Ceeta: Are you dirty now? I'm afraid I can't tell.
Footnote: Note: Sergeant Schlock's kind are usually classified as "carbosilicate amorphs," and by molecular weight they are essentially peaty, clay-infused hairballs. The 'hair' is actually carbon nanotubes filled with the complex molecular machinery of memory and self-replication, but what you see from three feet away is startlingly similar to the droppings of a very large, very healthy ungulate. Before you go lording it up over an amorph based on the fact that he or she is essentially 'peaty, hairy, clay," you should bear in mind that by the same rules you are a "bag of no-longer-potable water."
