what's that coming over the hill?

I decided to work from home today, and as a result I have had the TV on in the background to the best channel ever, the International Music Feed. Not only does it show music videos all day, no stupid shows, but it also shows international videos.

As a result I have had this song lyric repeating in my head all day: "What's that coming over the hill, is it a monster? Is it a monster?"

A google search turned up this amusing article: http://www.metro.co.uk/weird/article.html?in_article_id=56351&in_page_id=2
