December 1st: Duke decided to play fireman today. He squirted at Pop Rock three times today when he was changing him. At first it was funny and he got a new outfit and his blanket went into the washing machine. This second time it was a shame on me moment. The third time Duke got Pop Rock's feet and the floor.
