Prince William is usually the picture of decorum at royal functions. Yesterday was a cute exception. Anyone who’s gone to church has probably had a giggle fit there at least once. It’s funnier because you’re supposed to stay still and quiet. Prince William had a harder time because he was surrounded by Kate Middleton, Prince Charles, and the Queen. It was at the service to celebrate 100 years of the Royal Air Force.
