My ex-brother-in-law was famous for clogging toilets. Which leads me to this story.
I always puzzled over how he managed to block up toilets the on the entire east coast. Then while out fishing with him one day I found out. Before fishing we stopped at McDonalds for breakfast and headed down to the lake. Quite understandably we both had calls of nature at roughly the same time so we parted so we couldn't see each other through the trees. After completing the act be both bragged on the general volumn of waste created. Being the curious and bored sort (we hadn't caught any fish) we inspected each pile. Mine was the typical lincoln Log see-saw variety while his, continuing with building analogy, looked like what you would pour a foundation with. My brother-in-law produced the human equivilant of quick-crete. Mystery solved.
