David Wilson, from Victorville, California, shared this video on Facebook last month. Since then the video, and the story of his daughter's wedding, have been shared all over.
In August, Wilson's daughter Lisa and her fiancé Robert Pantoja moved their wedding to his hospital room.
The couple moved up the plans of their elaborate wedding day and tied the knot next to Wilson, who was suffering from a rare and terminal form of cancer.
Lisa told CBS that it sadly wasn't the wedding she had dreamed of since she was a little girl.
Pantoja told reporters that the special bedside ceremony really affected him. Wilson told him that he won the lottery and was lucky to marry his daughter.
As of this week, the video of Wilson sharing a dance with his daughter has been shared over 300,000 times with users from all over the world sending their thoughts and prayers to the newly married couple.
Sadly, Wilson passed away last week. His funeral was held over the weekend and his family has set up a memorial fund in his name.
