Haha hopefully you find your diamonds if you ever get to it.
I think my most memorable one was back in the days when I first played Minecraft. It was Minecraft Alpha. But more important, it was when I was so horrified of the dark and the hostile mobs. One occasion, I wanted to find ores (coal if I remember right) so I faced a dark cave to go in. After much hesitating, I slowly ventured a few blocks in when I heard a sound behind me. I looked behind to see what it was. There was mob against the bright background. I got so terrified that I hid behind a rock in that cave. That mob? It was a chicken.
