The dwarves dug too greedily and too deep. And also straight down.

"AAAAAAAAAA- Oh, look! Diamonds! -AAAAAAAAAHHHHHH!" *Hits lava*

Unless you're playing Death Swap and have balls of tungsten.

XKCD:
- "But the dwarves delved too greedily. And too deep."
- "And awoke a terror of shadow and flame?"
- "No, they just couldn't get out..."

Yep, I remember when this was how I actually found diamonds. Now I have a proper grid system that I do so well, I actually seal off any cave I come across so I can just keep tunnelling without interruption.

Minecraft was a lot more fun back when I was messing up. :P
