Man, the very first post of the thread is derisive, insulting stereotyping.
I get it - you think it's weird that someone, somewhere keeps a spear next to their bed instead of something like a loaded gun under their pillow. I'll grant you, the use of a spear is certainly kind of odd, as it isn't the most practical personal defense tool. But if you're a member if the Society for Creative Anachronism, you're a historical weapon enthusiast - if you have a spear on hand, it's probably because it's part of your collection, not because you actually plan to use it to defend yourself. And if you do use it to defend yourself, it's probably because it was the first thing to hand.
What I don't understand is why you think any of that deserves to be mocked, or why you associate weapons enthusiasts with the sorts of absurd negative stereotypes heaped (largely undeservedly) on LARPers, tabletop gamers, and other various sub-cultures that I can only assume you personally are mystified by.
I just don't see how any of that would seem relevant. A good friend of mine is a spear-fisher, and he happens to keep a homemade sling-spear underneath his bed (because where else do you put a five foot long piece of bamboo with spikes on one end?). If someone broke into his home while he was in bed, I imagine he'd be quite ready to defend himself with it if necessary. Would you crack stupid jokes about him if things came to that?
By all means, marvel at the oddity of this strange turn of events (I certainly am!), but please, please, please - stop making stupid jokes and perpetuating absurd negative stereotypes.
(Full disclosure: I am not a member of the SCA or a LARPer, although I am something of a historical weapons enthusiast and I've been known to play the table-top game "Shadowrun" from time to time.)
