Prince Harry announced last month that he'd be returning the favor of having his brother, Prince William, as his . William responded , "It feels great, a real delight ... revenge is sweet."
A look back at Harry's speech at the 2011 Duke and Duchess of Cambridge's wedding, gives a few hints at what William might have in store for his little brother and his bride-to-be, Meghan Markle.
"Harry said William was the perfect brother," one party goer told at the time. "It was exactly how you would expect a best man’s speech to be. He cracked loads of jokes about William. He called him a 'dude' several times. He kept coming back to it, saying 'What a dude.'”
Harry went on to say: "William didn’t have a romantic bone in his body before he met Kate, so I knew it was serious when William suddenly started cooing down the phone at Kate."
The speech included hilarious impressions of the newlyweds: a high-pitched version of Kate calling his brother "Billy" and of William calling Kate "baby."
Harry also poked fun at their grandfather, the Duke of Edinburgh, being dwarfed by Princess Catherine in her three-inch heels, reported.
Harry's toast was a hit with the couple, leaving Kate emotional, according to reports.
Harry reportedly worked on his speech with best friends Thomas Van Straubenzee and Guy Pelly and was prepared to tone it down if his grandmother, The Queen, attended. She ended up skipping the evening portion of the event, though.
William and Prince Charles had their moments to poke fun earlier in the weekend at the wedding breakfast.
"The thing about growing older is that your children get taller than you so they can see your bald spots. Now in my case, I can see his," Charles joked about William, The Mail on Sunday reported. William responded: "You got there before Harry!"
William and Harry's speeches both reportedly included references to their late mother, Princess Diana, as well.
When his speech was over, Harry, in a pro best man move, insisted that bacon and sausage sandwiches were available at the end of the reception, The Telegraph reported.
