I am surprised by this rating, first because the jokes are so specific to a certain 20 and 30 something subculture, but secondly, because Portlandia contains skits that make even me (a 37 year old adult) uncomfortable. For example, in the "Cacao" sketch, Nina and Lance try a variety of unusual positions which elicit their safeword (cacao) over and over again. In typical Portlandia fashion, this scene goes on and on. It's excruciating to watch- I can't imagine watching it with kids. It's creepy.
