There's this cheesy mermaid doll, by a company I've never heard of, with colour-changing hair (fakey-blonde to fakey-pink) that sings every time it comes out of the water.

Having now heard its song six times, only on the commercial, I can say with some confidence that the doll will last roughly nine minutes in the standard family household before being trampled to bits by parents and children alike. So, so annoying...
