Not really a Darwin Award but could have been one ohhh so easily...
So I went searching for the End for the first time and, as usual, I forget to give a damn about what's in my inventory before I set out, so I get there, go to the end, open up my inventory, turns out I'd brought my entire stock of Ender Pearls (about 8 stacks at the time) all of my blaze rods(couple stacks maybe), 12 enderium ingots and half a stack of diamonds... "It's fine, I have my super awesome bow with infinity and power V and flame and all this ridiculously painful shizzle!" "Hmm, why can't I shoot arrows..?" no arrows in my inventory... balls...
So I whack one of the egg things, 5 hearts of damage... no good...
So what do I end up doing? I fly up to Y600 or so (mek jetpack how I love you so!) and start duelling the Ender Bitch in the skies! If I'd died I'd feel hugely stupid, but I won
first time I ever found and killed the Dragon
