This thread is to trade and discuss outlandish, dangerous, expensive, painful, and stupid actions taken on by you, or someone you know... for the lulz.
My best one was when me and a few friends went to this horrible little beach hut (it was a shed with filthy beds in it and old style fridges that didn't work so well, out in the bush)
They told me that coconut milk was flammable. I swore black and blue they were wrong, so they went out and got a coconut from the sand, and lit it on fire. I apologized, and admitted I was wrong, and then they revealed that they had filled it with spirits and stashed it there.
We all laughed, and then they get it in their heads to play soccer... let me set the scene for you. We are out in this filthy hut, which likely has spiders and snakes, surrounded by black sand, the dirtiest kind, all barefoot, and a thousand miles away from a ROAD, let alone a freakin' hospital... and these guys start kicking around a ball of flaming spirits.
And they weren't content with just soccer... my little brother played hacky sack, and bounced it from knee to knee until OMG HOW DID THIS HAPPEN?! His pants are on fire! Being on one foot at the time and horrible off balance, he launches into the air and lands on his cheek, exactly the opposite of what he was trying to douse.
After having the flames beaten out, he gets up and continues the game like nothing happened... it ended when my friend Dallas got third degree burns all over his foot and ankle. I went inside to find the first aid kit, and found a rusty metal box with nothing in it but an old bottle with a faded label... this thing was a tetanus risk, not a medkit!
I took it outside, dropped it on the ground, and walked over it (Halo reference. They laughed) this poor guy went 5 days with only Vodka to stem the pain, and when we went home, mum offered to drive him to the hospital... and he declined to play World of Warcraft.
So share you Jackass inspired or just generally idiotic drunken trips to the hospital here.
