From the pages of twinlog:

We've been watching a lot of Rolie Polie Olie. Elizabeth came in and asked, "What shape am I?" Olie is round and Billy is square. I told her she was potato-shaped. She didn't think so. So I suggested curved and she agreed. But Wil and Daddy are round according to her. In actuality Wil is shaped more like a stick.

What about Daddy?! Is Daddy round?!

Boo hoo hoo.
