The other day, Peter called to me from the downstairs powder room and said, "there are rocks in the toilet!" I followed him in there and he pointed into the bowl. "You can't see them all the time but after you flush, they sometimes creep out." I look and see a few pebbles where the pipe disappears into the recesses of the commode. "Well," I say, "stick your hand in there and fish them out." "No way!" "Yes way! I keep the toilet clean. Those rocks just aren't getting past the trap."

After some discussion where he didn't even want me to put my hand in there, I go get a couple of paper towels and start fishing out rocks. These are pieces of gravel about 1/2 inch or more in diameter. They have obviously been digested by Rockwell and then, due to their weight, not been able to make it past the trap in the toilet. I end up pulling out almost a cup full of the things. I'm guessing that Rockwell has not necessarily been on a recent rock-eating spree but that they have been accumulating quietly all year and we've only just noticed them now. It was however, an impressive haul of rocks.
