"After an hour or two I was tired, and relieved when someone shouted that lunch was ready. We had a big picnic in a large, airy barn, then trooped off to a makeshift shooting range. When everyone was bored of firing rifles, they dressed me as a giant yellow-feathered chicken and sent me downrange to shoot fireworks at me."
However, Harry was careful not to get "too drunk and pass out" to prevent William from shaving his beard.

This may be one of the most raucous royal hen parties we've heard of! For her hen do in 1986, Sarah Ferguson and a group of friends including Princess Diana dressed as police officers for a night out in London, but were reportedly quizzed by authorities outside Buckingham Palace as it is an offence to impersonate a police officer. The group ended their night by playing a trick on Prince Andrew and locking the palace gates. Writing in her autobiography, Sarah said that she confided in the Queen about her wild night out, who thankfully found the events "reasonably amusing".
