Queen Elizabeth II was known to have a brilliant sense of humor. Whether she was pranking American tourists in Balmoral or allegedly impersonating Melania Trump, the Queen's wit was well documented. It also appears that the late monarch carried out some amazing surprises, such as turning up at a stranger's wedding at the last minute.
As reported by the Daily Mail, Frances and John Canning sent a wedding invitation to Queen Elizabeth II in 2012, purely because they had one spare. It transpired that the Queen would be attending an official engagement nearby on the same day, so she planned to put in an appearance at the couple's nuptials.
