Princess Diana and Prince Charles

In anticipation of Friday's royal wedding of Prince William and Kate Middleton, TLC will air Charles and Di: Once Upon a Time (Sunday, April 24, 7/6c), which is essentially a Pop-Up Video-style rebroadcast of the 1981 wedding of Prince Charles and Lady Diana Spencer. In this exclusive clip of the special, relive that special time in pop culture history when Lady Di said her husband's name wrong on the altar. Only at a royal wedding could something like this create a mini-scandal after, but then again, only at a royal wedding would the groom have that many names.
