Did you get close enough for that picture?
Were you doing an autopsy?
Is oriental grease is the stuff they put on those sticky rat traps? We lost all of our scrapers in the first oriental job we did, from then on we chained to ourselves before we started working, but a OSHA guy came around and told us that was to dangerous because if the scraper got stuck and we were chained to it we may die there. Oh I hadn't thought of that! So now we mostly just avoid them.
