Homer Simpson sings a song on 2003 and Usher releases a song years later that sounds very similar. The following video plays both songs separately and at the same time so you can notice the similarities. Simpsons are known for their inventions and forecasts like touchscreen devices. I believe Usher or whoever wrote the song was watching Simpsons. Enjoy the video and start watching Simpsons since you might also find something useful!
