In his sharp suit and tie, Prince William looked every inch the city slicker.
But standing next to Batman and Robin, the Joker and Wolverine, he didn't exactly fit in.
The second-in-line and his father Prince Charles were at international brokerage firm ICAP to help out at the company's annual charity fancy dress day.
And William impressed when he managed to secure a £14 billion deal between two major banks as he manned the phones.
The commission from the deal will go to a number of charities including Skill Force - which provides training for underprivileged children. The newly-engaged Prince is their patron.
