The best kind of elderly person is the kind with a sense of humor that not afraid to have some fun and "gets" the joke. Take this hip grandma for example. She understands that people watching a 70 or 80-something year dance a choreographed routine to Usher's You Make Me Wanna is funny and she's more than willing to participate.

What's even better, is that she's actually pretty good! My assumption is that this little ditty was rehearsed a number of times before it was filmed, but nonetheless...grandma can get down!
