Proof That The Olympics Is The Most Fun Kate Middleton Has Had All Year

    Just compare her Olympics guffaws to her expressions at other events.

    Here's Kate Middleton watch sprint track cycling at the Olympics.

    And here she is while Prince William makes a speech at a reception.

    Here she is at the Equestrian Jumping event at the Olympics.

    And here, leaving a Cathedral service in honor of the Queen's Diamond Jubilee.

    Track cycling at the Olympics? LOL.

    Stuffy royal gathering? Snooze.

    Olympics horse-jumping: a hoot!

    Riding in a horse drawn carriage through London: a drag.

    Here's Kate's reaction to watching Olympic handball.

    Here's Kate's reaction to watching a non-Olympics "sports demonstration" by children.

    All laughs while watching royal cousin Zara Philips compete in the individual equestrian cross country event at the Olympics.

    No laughs here, at an event at a museum.

    At every Olympic event, tons of cheering.

    But even at Wimbledon, a non-Olympic sporting event, she was sour-faced.

    Wimbledon: bad.

    Show jumping: hahahaha!

    And here's how she looked while doing crafts with kids.

    A cross-country equestrian competition elicited a toothy smile.

    Painting with a cute little boy did not.
