Playing Minecraft with Beelzebub
Basically, me and 2 friends were messing around when I decided to pour lava on top of a hill, which flooded a large section of the valley we were in. Me and radek continued to do this to the remaining hills in the area, and right after we were done, radek took away our admin-powers (teleporting, spawning items etc), and starts teleporting us into various deathtraps (which is funny since we couldn't actually die).
This went on for like half an hour, and goddamn did we laugh.
