At dinner this evening we were talking about Michael Jackson's moonwalk. David decided to get down from the table to attempt it. After being told to sit down (because he hadn't been excused from the table) he got back up to attempt it a second time, then a third. After the third attempt he lay across the arm of a chair in the living room. I said "You're doing 2 things wrong" (meaning being down from the table without being excused and laying on the arm of a chair) "Can you guess what they are?". He quickly said: "I'm picking my feet off the floor?".
