Mommy - guess what???

I peed in a cup.

Why would S pee in a cup? And why would he announce it at Christmas Eve dinner? Apparently Trinks was taking a milisecond too long to pee, and the cup dispenser was so handy. And he managed to fill the Dixie cup, dump it, and fill it again. My first thought was, if the toilet was free to dump the first cup, why couldn't he have finished peeing in the toilet? I guess it was too much fun. He seemed especially proud of himself.
