Boys are funny.
Jack and Gus are always involved in some kind pre-school style of play that is always entertaining. Today they are in the middle of a game they made up called Earthquake:
Jack: Did you know there was an earfquake in San Antonio?
Jack and Gus: EARFQUAKE!!!! (Gus and Jack throw themselves on the floor, wiggle around and yell for 30 seconds.) Afterwards they stand face to face and cry out at the same time: “I feel dizzy!” They then fall backwards and lay flat on their backs and giggle uncontrollably as if they were the only ones to hear a really funny joke.
Then it starts all over again, and again, and again. What joy!
