Uncle D time

There is a legend, that goes something like this:
Many years ago, a young boy hated his chores. At he appointed time, he ran to the bathroom for an extended stay to get out of his chores. To this day, it is said that his elder sister is still quite bitter about it. This boy will be reffered to as, "Uncle D." in these pages. The names have been changed to protect the guilty.

My daughter, referred to in these pages as "the girl." has picked up this habit. We call her out when she does it by saying she pulling an "Uncle D." During dinner tonight, my son got up from the table and walked away. He was asked to return and finish his dinner. His response?
"It's Uncle D time, it's Uncle D time," he said while jumping up and down and clutching his buttocks. He then ran into the bathroom for an extended stay. The legend lives on.
