Explanation: LazyTown is a children's television show that comes out of Iceland and teaches kids that eating healthy, exercising, and making healthy choices in general (brushing teeth, being nice, et al) can be fun. It's a bright and colorful show that uses Aqua-esque techno songs, puppets, dancing, and live action to get its message across. Yes, it comes on Nick Jr, but it also has a large adult following because it's one of those shows from which you can't look away. Plus, Magnus Scheving (who plays Sportacus, the superhero) is a total hottie.
The "odd couple" in the icon are: Sportacus, the superhero, on the right and Robbie Rotten, the villain, on the left. In this particular episode, Robbie disguised himself as Sportacus, and when the two met, they started dancing together (for what reason, I can't remember).
A superhero and his "nemesis" dancing? I'd say it's an odd couple.
