When it comes to buying a present for the person who has everything, what do you get? The Royal Family are notorious for their funny tradition of buying each other gag gifts at Christmas time, with previous presents including a leather toilet seat, a 'grown your own girlfriend kit' and even a shower cap which had “Ain’t life a b****”. While these gifts are supposed to be utterly bizarre, there is one present that Prince William bought for Kate in the early days of their relationship that she has apparently never let him forget.The Prince of Wales revealed what the strange present was on a podcast with Peter Crouch.
