Special Agent Duke

Is it wrong that the boys new favorite toy is a brown paper bag with a face of a cat drawn on it?! They have named this "cat" Duke, after my sister's cat. It is hilarious, they talk to this "cat" as if he were real and actually do the things that Duke asks them to. Yesterday, Duke got Derek to go number two on the potty. He was so proud and wanted to report back to Duke, so he says "Mommy, will you wear Duke?" It is too funny. I'll have to try and get a picture of Special Agent Duke up.
