The traditional father-daughter dance at weddings can be emotional for not only the bride, but for everyone else in the room. This bride had possibly one of the most emotional and touching father-daughter dances on her wedding day, after her brother talked about their late father, who passed away from pancreatic cancer, and surprised her by singing "Butterfly Kisses" as she danced with her closest family members. The video is from 2012, but has gone viral this week. Let's hope she had waterproof make-up on!

Caution: You may want to grab a box of tissues, because it's hard not to shed some tears (or a lot of tears) over this one. Watch below.
