Hahahaa!
But seriously, what major breakthroughs in toilet technology have there been in the last 100 years? Sure, you gotcher automatic flushers and your padded seats and such...but the basic principle of the Crapper, how much could it be improved upon that we need to test it with fake poo?
For one thing: they are paying people to make fake poo when it's an unlimited free resource.
For another, what's the goal: gentlemen, we need to see exactly how small we can make this hole while keeping it capable of accomodating the average-sized poo. I want everyone on this project. Betty, call the Poo-man and make sure he ramps up production. The competition is draining all our profits.
Lastly: if your poo is always the same length, circumference, and consistency, I'd advise you to stop with the steady diet of packing peanuts.
