Wedding Reception Using A DJ

I was recently at a bridal show and caught the tail end of something done by the dj. It appeared that the dj had the couple (bride and groom) out on the dance floor in front of their guests and were asking them questions. For example to the groom, "What was the first thing you noticed about (name)?" Then the dj had a song clip that played. For this question it was "my hump, my hump, my hump song. Another question was for the bride and groom, what would you like to see happen now? song was "Let`s Get This Party Started". Is anyone familiar with this and if so what were some of the questions and songs to go with them? I would love to get more information about this but haven`t been able to find anything on the internet. Any help would be greatly appreciated.
