and they'd get the razor blades form the bunnies being shaved by gillette labs...

I took Experimental Psych junior year at A&M . The instructor was conducting research using rats. She'd dispense cocaine to different groups and document what behaviors they were willing to shut off to get the stuff. Almost without exception these rodents consistently chose cocaine over food, water, sex; just about everything would be secondary to getting their rat blow.

I imagine rats are fairly manually dexterous, but for the life of me I can't picture the little creatures with a razor blade and mirror. Of course capillary tubes would be the only thing small enough to snort it with. Then they graduate to rock, then on to a life of rat prostitution. Very sad cycle.
