Ultima Online: My brother and I were going through a very large haul of loot we had picked up on a murder spree we had just come back from and noticed that our treasure chests were strewn about the house in a pretty disorganized manner. So we began rearranging the house into "chest sections". One section for armor, one for weapons etc. As we're going through the boxes and moving items from one side of the house to the other (sometimes passing items off between us) I find one of my booby trapped "lock boxes". (These boxes were used in the game as a way to get the last laugh on a murderer player, it would basically spring a trap when someone would loot the box off your corpse and try and open it to find any goodies you may have put in it) and decide to hand it to my brother telling him that it was a box full of spell reagents. Well he doesn't open it and instead takes the box to the other side of the house. (Back then there really wasn't ventrilo so we were on the phone talking to each other the entire time) so to get him to open it, I say "Oh hey bro, I left a couple of metal ingots in the box, do you mind handing them to me?". Two seconds later there's a huge explosion in the house and his body hits the ground with a thud.
The laughter was the kind you can't breathe and feel like you're going to pass out from lack of oxygen..... coming from me and him.
