We all knew that town was not a safe location in Diablo III (until v1.0.3 put up barriers), and you often heard jokes about leading monsters into town and trapping the waypoint, but did anyone actually do it? Yes, actually.
GiantKiller shared in the forums links to a lengthy and largely-humorous illustrated saga of massive town trapping. There are dozens of screenshots showing off the chaos and the deaths of players joining the game, all of whom were no doubt cheered in their seconds of surprised terror by jolly messages about “welcome to the zoo please do not feed the animals.”
The softcore version is pretty amusing, but they posted a Hardcore one as well, which is less amusing. Or perhaps more amusing, depending on your perspective.
