Guests had been expecting good things from Prince Harry's best man speech. And true to form he had them in hysterics from the word go, by referring to his brother Prince William as "a real dude"
The flame haired royal is said to have donned a Fez hat before he stood up to speak at the evening reception at Buckingham Palace, which was attended by 300 of the couple's close friends and family.

Harry apparently couldn't resist poking fun at William's receding hairline, and joked how "William didn't have a romantic bone in his body before he met Kate".
He continued: "So I knew it was serious when William suddenly started cooing down the phone at Kate."
William's brother had been fine tuning his speech for the last fortnight with some help from his on-off girlfriend Chelsy Davy and his two best friends Thomas Van Straubenzee and Guy Pelly.
Finally he decided to drop some of the racier material, including a reference to "Kate's killer legs"
“Harry had some joke in about how he had immediately given Kate the thumbs up when William first brought her home because she had such a great pair of pins, but he didn’t want to embarrass her,” said a friend.
Jokes aside, there were also touching moments in the final edit. Harry told how he loved Kate "like a sister" and how he thought of her relationship with William as inspirational.
His new sister-in-law is said to have been deeply moved by his tributes.
When it came to William's turn to speak he called Kate Mrs Wales. And she'll have to get used to that name since at the RAF base she'll be expected to mingle on wives' nights where he's Flt Lieutenant Wales.
Guests listened from their seats at 30 circular tables, decorated with pretty white flowers, and named after the newlyweds' favourite places.
These included was Rhoscolyn – a village on Anglesey – and Maun, a town in Botswana that Prince Harry calls 'home' on his Facebook page.
After the speeches, William took Kate's hand and shyly led her onto the dancefloor for the first dance, which was Your Song – the Elton John number performed by Ellie Goulding.
The pop ballad singer was the only artist to perform at the reception.
After the slow dance, she got guests moving with more upbeat numbers, including Blame It On The Boogie by the Jackson 5, Summer of ’69 by Bryan Adams and Superstition.
Once Ellie had sung her last number at 1.30am, a DJ took over playing dance music and hip hop.
As the night went on the new Duke and Duchess of Cambridge are said to have let their hair down, with Kate taking off her bolero and dancing the night away in her strapless Sarah Burton dress.
By all accounts the newlyweds were hardly off the dancefloor till things wrapped up at 3am.
The pair retired to bed, but a crew of guests – led by Prince Harry and joined by Princesses Beatrice and Eugenie – went on to an unofficial after party at the Goring Hotel.
Some guests have described the evening celebrations as "the party of the decade".
