If you find yourself climbing into bed right after you put your kids to sleep and can no longer relate to anything the "youngins" are into, the Holderness family [1] is about to put all of your feelings to music through a laugh-out-loud parody video [2].

Set to the upbeat tune of Justin Bieber's "Sorry," Penn and Kim Holderness sing and dance about what life looks like at 40 — when you're not exactly "down with the kids" anymore. Between Kim's hysterical dance moves and Penn's all-too-real lyrics, this video is not only making us crack up but also understanding and validating our struggles in a very real way.

If you are still confused as to what "twerking" means, leave your house for a night out at 5:30 p.m., and continuously break out the dance moves you used in college, you need to watch this video, as it's going to resonate with you on a deep personal level.
