Oh my. He is cracking jokes. It is amazing; well it is amazing to us. It’s one thing for him to cackle when tickled or when we make goofy faces: it is another world entirely now that he is making the jokes. Joke 1) Place anything on your head (hold it there if it doesn’t stay on its own), wait a second, and then say ACHOO and let the thing fall off. Instant hilarity. Joke 2) A simple consonant switch. If the words are “milk, please”, say “gilk, gease” instead. See? I told you he was funny.
