Bobbing for 'bobbies!'

One day I was checking my email and the kids were playing. Sydney was playing nicely in her room, and Mac was running from room to room. I know I should have been right with him, but I just wanted to check my email. Then I noticed that it was quiet, which is never good. Then I hear Mac flushing the toilet in my bathroom. I called for him to come. As he rounded the corner, I noticed that his forehead was wet and he had a pacifier, aka 'bobbie,' in his mouth. He escorted me back to the toilet, which was running, to show me what he had been doing. Yes, my son had been bobbing for 'bobbies' in the toilet!!! Needless to say, we bought some new 'bobbies!' Disgusting!!!!
