Pyramid head man. Spotted again!

So, I've heard people talk about and seen posts about a man with a metal pyramid on his head. I've heard he's usually spotted around Central London; Oxford Circus & Leicester Square appear to be the hotspots but I saw him in a suburb of North West London...

I must say, this pyramid thing seems to have great healing powers. Whatever these powers may be, perhaps I should try it out. I don't think I'd get one, for I am only 17 and would be the ridicule of my school and my peers would never take me seriously again. Besides, as I'm hoping to go to medical school, I don't want people directing me towards psychiatry, do I? Understandably, there's belief behind the obvious wearing of this pyramid, but I don't know enough about it to comment. However, I'm sure others would comment prior to finding out exactly what this contraption is and hence my probable insecurity if I were ever to wear one.

The gentleman I saw was wearing a grey/green smart jacket and... well, the pyramid. He was standing on the bus, quite far from me, supposedly on his way home from work or something. It just seems strange that society has a stereotype of people and that these things stand out. This includes me, but I suppose that these rules are governed by society and anything out of the norm is a bit of a shock. Thinking about it, with more than 60million (it was this figure in 2001, probably a LOT more now) people in the UK, surely we can't all fit into the mould of "human"?

Anyway, I don't want to let my ramblings take over this post. I wonder what the pyramid is all about, how this man found out about it and started wearing one? He seems to be a popular sighting out and about, but surely, somewhere out there there's got to be someone else? Don't let me stop you from telling me all about these pyramids. They may work miracles on my health!
