Yahah. On my server once, there was this spamming noob who kept on spawning planes so they hit houses and flung themselves away (glitch). I F8'd him into my cottage's roof crawl space and all you could see is his head sticking out of the roof. Lol :D
EDIT:
There was also someone building a house next to mine, and under the house was kinda like a 3-brick crawl space, with no door. I F8'd him in there after, and he got stuck so half of him was stuck in someone else's floor forever.
