My son.

Last night when the kids were getting ready to leave for Mom's house, Aidan was asked the following question: "What shape is the back bedroom in?" the back bedroom being the impromptu playroom for the kids, and it tends to get destroyed, you see. Aidan answered in the following manner (I will spell it out the way he said it, as it will be important later) "Um....wecktangle". I almost wet myself.

When Abby came into the room to find us all laughing like idiots, she asked what was so funny. I told her what Aidan had said about the room and she laughed as well, and then said - wait for it - "Wecktangle, that is funny, because it's 'rectangle'"
