In the early days, when the summon/gank ruled Thera, it was not possible to open a door while blinded. Thus, the necromancer/anti-paladin above-shop summon/blind was quite common.
I remember the old Diku days of global summon, as well- everyone meet up in the Shire (old Shire) and run to the Thain's room, summon backstab trip trip trip Violets are trip Violence is a trip omfgz0r I'm profound. And old. <insert witty Java follow-up>.
