Just had one today...
I created a trap using redstone, and redstone repeaters...
The only way in my box was to destroy a dirt block above...
I have pistons layed next to my mine...
I pulled the switch and the chest flew upwards into the cieling of my house and the guy was pissed... I couldn't stop laughing!
When I build my houses I always make the self destruct switch first...
He pulled it thinking the chest would go back down...
I pulled the switch off that goes to my iron door, thus, closing it...
My house was made of stone, and he had not enough time to escape while I hid in my mine (Next to my house)
I saw, "SHIT" on the text bar below...
The tnt exploded...
Some of my stuff survived including my diamond pickaxe collection...
I was awarded the chance to invade HIS house which was underground next to a dungeon...
It looked REALLY crappy...
I broke the door and stole it...
I saw a sign that said, 'My Stuff, Keep Out!"
I broke it and wrote... "Bite Me"
I then placed 8 blocks of my tnt and pulled a redstone switch outside his house as I waited for his arrival...
He saw me on his way down and hit me with his wooden sword...
I ran after pulling the switch...
It blew up killing his house and him...
I had a victory laugh...
A creeper exploded...
I died and became sad...
The guy who was in this fued with me mocked me and insulted me for being killed by a creeper while he is naked and walking around without the knowledge of crafting...
I had another victory laugh as he insulted me one more time and left...
I collected his materials and got revenge on the creeper...
THAT was my 5 hours of MC for today
