The Duncan's video, "The Fresh Prince of Phoenixville," already has more than 55,000 views.
The video was shot in Phoenixville and around Temple University, and was posted to YouTube by MerryweatherFilms.
The Duncans, Dayton and Melanie, met at Temple and they've been together for seven years.
"We decided on the video because we thought it would be something different than traditional reveal pictures," Dayton told CBS Philly. "It's different, a little more captivating, and we thought our family would like it better. We came up with the idea and ran with it."
Although there is a joke in the video about Dayton hoping the baby will be a boy, there's also a caption that reads that a girl would "be cool too." The baby is due in November 2014.
"We were having fun with it, hopefully everyone enjoyed watching it," Dayton said.
