If you're Happy and you know it then clap along with Pharrell Williams to this uber-annoying song with little or no artistic fladulation. On the original cover we see Mr Williams though he is not looking particularly happy as he appears to be either doing an impression of an aeroplane, or balancing precariously on some unseen wall. On the remix, we have a happy looking lady with happy looking balloons. Oh, and she is doing the kind of balloon dance that we like, what about you? Happy?
