"I want cake!"

Joey usually seems to want to talk as little as he possibly can. He will use single words or even single syllables if he can get his point across. So, today out of the blue he decides to talk in full sentences! After dinner, I said to Dave "Oh I forgot we have leftover cake" and Joey said "I want cake!" clear as day. Then he repeated it "I want cake!" It was so funny. It makes me feel better because I was starting to worry a little bit that he would never talk.
