Dennis & Judi love Pharell William's hit song 'Happy.' It's just a catchy tune that puts you in a better mood no matter what's going on. There have been a few groups of people that have created 'Happy' videos but this one may be the best yet. A group of seniors at a retirement community decided they wanted to show their family and friends just how happy they were, so they all got together and made a lip dub video to 'Happy' as well.

Check out the video below.
