The non-toad

Just got back from a nice walk around the neighborhood with my husband.  It was dark, and the kids were in bed.  We saw a robin sitting on a nest, and several rabbits, and we could hear frogs croaking.  On the way home, I saw something on the sidewalk that looked just like a toad, so I stopped to look more closely.  My dear husband said, "Is that a frog or a toad?"  I picked it up.  It didn't move.  In fact, it was neither a frog nor a toad.  It was a turd.
