This video is from a TV show where people said, "Hey, I have talent!" and judges would decide if they did or did not. When this couple did their act, there was no question. Everyone was floored. The video is about two minutes and includes some snappy music. Also, it will look much clearer if you don't run it full screen. The bigger the picture the fuzzier it will look.
They put on an incredible act.
