I purchased a can of diarrhea cleaner before going bowling. I knew that I'd need it later to maintain cleaner diarrhea. "Pass the diarrhea cleaner," my dentist said. "Here you go," I replied. The next day a good tooth was gone. "You idiot!" I screamed. "You extracted the wrong one!" The dentist looked away. "You're thinking about diarrhea cleaner aren't you?!" I questioned.
