Britain's Catherine, Duchess of Cambridge, holds onto the hand of her husband, Prince William, as she bends down to pull the heel of her shoe out of a drainage grill.

Catherine, Duchess of Cambridge, is not immune to awkward situations in heels, but at least her husband, Prince William, is there to lend a hand as she attempts to free herself from a drainage grill at Mons Barracks in Aldershot, England, on St. Patrick’s Day.

The duke and duchess were there to present sprigs of shamrocks to the 1st Battalion Irish Guards during the St. Patrick’s Day Parade, a tradition started in 1901 by Queen Alexandra of Denmark, the wife of King Edward VII, who took the throne that same year.
