Seriously, all you need to do is look at the sales numbers for Ubisoft's Just Dance series — the latest entry of which, Just Dance 3, has already surpassed seven million units with no signs of slowing.

That puts the franchise's total sales at a whopping 25 million units. Admittedly, there have been a ridiculous number of entries into the series since it launched — and the numbers include spin-off games such as Michael Jackson: The Experience — but the figures prove that people really do enjoy embarrassing themselves in their own homes.

We just don't get it, and we never will.
