What's your biggest fail on MineCraft?

What's your biggest fail on MineCraft?

I guess i'll go first.

I was just walking around, in the dark.
Suddenly I heard a SSSSSSSSSSSSS noice, it was a creeper.
I ran and survived it, then another creeper comes out while I try to get to my house and blows up part of my house, but I survived...
Then a zombie fucking spawns next to me and kills me.

i was just casually walking in my house and all of a sudden OMGWTFRANDOMHOLETOHELL
yeah lava hole

lol, I was digging a 1x1 tunnel down, and discovered lava.

Ehm, I played on my server, was going to the nether put I had to enable it so I did and restarted my server. When I loaded the multiplayer I spawn in the nether and no portal, and my 2 friends on the server died and lost everything, so I was walking around for hours until I killed my self and spawn in the minecraft world :/
