In 2011, at Prince William and Kate Middleton's wedding, Prince Harry, the Duke of Sussex, was designated as the best man. However, Harry recently disclosed that he wasn't allowed to deliver a full best man's speech, instead introducing the actual best men, James Meade and Thomas Van Straubenzee, who gave the traditional speech at the reception. It has also been revealed that a potentially embarrassing comment about his new sister-in-law was removed from his original speech.

After the ceremony at Westminster Abbey, the newlyweds and their guests proceeded to a private reception. Prince Harry delivered a short speech, entertaining the guests with jokes about his brother and sharing heartfelt stories about the couple's love, which moved Kate to tears.

However, royal expert Katie Nicholl, in her book "Harry: Life, Loss and Love," revealed that Harry had initially included a daring joke about Kate's "killer legs" in his speech. Chelsy Davy, Harry's then-girlfriend, reviewed the speech before the wedding day and advised him to remove the cheeky comment, deeming it inappropriate.

Prince William reportedly got his chance for revenge when he delivered his best man's speech at Prince Harry and Meghan Markle's wedding in 2018. A guest at the wedding told the Sunday Times that William made a risqué joke about wet underwear in his speech, but the details of the joke remain undisclosed.

Additionally, Prince William played a prank on his brother during the wedding reception, tying a ladder to the back of the newlyweds' car, referencing a recent incident in which Harry had fallen off a ladder while changing a lightbulb.

Harry's friend Charlie van Straubenzee also spoke at the reception, teasing the prince about his red hair and sharing a story about Harry's time as a dorm monitor at Ludgrove School in Berkshire, where both attended as students.

In his memoir "Spare," released earlier this year, Prince Harry recounted events surrounding his brother's wedding to Kate in 2011, claiming that William was tipsy on rum just hours before the ceremony. According to Harry, his brother had been drinking to calm his nerves and even greeted people camping outside Buckingham Palace on the Mall while intoxicated.
