The Royal family are famous for their love of rules and when it comes to how they celebrate Christmas, it was an unusual tradition that caught out newlywed Diana.
From opening presents on Christmas Eve to weighing themselves before and after the main family meal, the Royals' long list of holiday traditions can be hard to keep track of.
It was something Princess Diana struggled with during her first Christmas with her new family in 1981.
The princess was unaware that all gifts given must be of the cheap and cheerful variety, the funnier the better, the Mirror reported.
