Maneki Neko Dakku まねきねこダック

Aflac Insurance have these adverts in Japan featuring a dancing duck and cat. They are so popular that a full length version of the song was released - complete with music video. The animals are fake and cheesy but it is cute and the song can be really catchy. I just love how it is completely acceptable (and expected almost) for things to be cute, even when aimed at adults - because I am pretty sure it is not the kids buying insurance in these ads.
