The parents of a 6-year-old boy had thought him deaf and mute. He had never spoken a word. Finally, one morning at breakfast, out of nowhere, the boy says "Oatmeal's cold."
Mom and dad look at each other in disbelief; finally, the mom says "Son, all this time we thought you couldn't speak, why did you speak now?" The boy looks at them and says "Up to now, everything's been OK."
