I'm glad I'm not the only one who saw that.
A friend and I were staying with my mother for a few days when my nephew was about two. I was spending some time with him one day, when he comes walking out of the bathroom chewing on her toothbrush. Turns out that he wanted to brush his teeth. Since he couldn't turn on the water, he just dipped it in the toilet. Needless to say, she got a new toothbrush.
