Some of the best Portlandia sketches are pseudo-commercial types where characters attempt to sell not just a product but a way of live to us. In this sketch, twins Marcus and Madeleine attempt to sell us recycling, their particular brand of recycling, and it comes off great. The constant asides, the subtle music cues, and the hilarious prop at the end make for a great sketch.
Another brand of great Portlandia sketch centers around people attempting to remain cool or hip. We saw this same idea last week with the running "Motorcycle" sketches, and we see it again here, as recurring characters Dave and Kath try to go for a hike but never quite make it.
