What's the obsession about flaming pieces of charcoal?

I do have a counter on my website, though it's invisible. What's fascinating to me are the routes by which people end up on my website. Besides the regular readers (some of which I know, most of which I don't), I somehow end up on quite a few google searches. Do you know what the most common one is? I apparently come up quite a bit when you google 'heap burning coals on head' (try it!). What makes me wonder, however, is why so many people, all over the planet, are googling that particular phrase...
