Having a little fun with charity! Prince William and Kate Middleton attended the ICAP 23rd annual Charity Day in London on Wednesday, Dec. 9, and hopped on the phones to help stockbrokers close deals with traders.

The Duke of Cambridge got into the spirit of trading and urged the brokerage firm’s clients to make bigger deals, at one point even yelling into the phone, “Is that all, James? Is that all you can do?!”

The 33-year-old duchess, who was dressed in a L.K. Bennett “Davina” power suit and showed off her new shorter ‘do, was more reserved and polite, often greeting traders with a “Good morning, how are you?” But she may have been even a little friendlier with one trader, and her husband of four years couldn’t help but joke about it.

After eavesdropping on one of the deals Kate was making on the phone, William, 33, teasingly chided, “Catherine, I think you can stop flirting with them now!” He then turned to a trader standing nearby and said, “Sorry, my wife is just embarrassing me!”

That wasn’t all the fun that the royal couple, who are parents of Prince George, 2, and Princess Charlotte, 7 months, had at the ICAP offices. Many of the brokers were dressed up in costume, with various desks featuring different themes. At one section, the men sported dress shirts, suit jackets, hot pants, and high heels. Other themes included Day of the Dead, Hollywood, and Scotland. At a basketball-themed section, the duke and duchess shot some hoops, with William landing three in a row, and Kate missing her first two shots.

The prince also goaded his wife a little to show her competitive side while touring ICAP’s offices. The pair played a game of Ping-Pong with the table set up at ICAP by SportsAid, one of the charities that the duchess supports, and a beneficiary of Charity Day.

“Come on, let’s try and have more than a rally of more two goes,” William teased. “You’re not normally this polite when we normally play!”

“Or this quiet!” Middleton replied.

Each year, ICAP donates a day’s worth of its revenues and commissions to various charities. This year, the royal couple helped the brokerage firm close $547 million worth of deals on Charity Day, and some of the money they helped raise will go to SkillForce, which counts Prince William as a patron, and Place2Be, along with SportsAid, which are two charities that Middleton supports.
