If anybody's interested, The "hone gumi" (bone group) of AKB48 is doing the "hone waltz" (bone waltz) on NHK's "Karada de asobou" (a sports show geared towards kids). Link:

They were also featured in Downtown's show "LINCOLN", when a member of the comedy duo Summers had to learn to dance and sing with the members, on his 40th birthday. It's not on YouTube, unfortunately, but it was absolutely HILARIOUS!! The girls were quite nice with him too.
