Carter frequently seems to find himself doing things like this. He just walked up to me with a "Easter Bunny" Mr. Potato Head piece in his mouth. He has the goofiest sense of humor.
The other evening he decided it was 'naked time' and proceeded to run around one of the sofas over and over. After about 5 minutes I said it was time to go get dressed in his pajamas. "Sorry Mom! Can't stop!" was his answer. And he didn't. He kept running for about 5 more minutes.
