I remember when people were doing the Last Curse quest step imprecation where you had to get head shot kills. Any time I would see someone using Imprecation I would run up to them and let them shoot me in the head and then respawn find them and do it again. I remember how much of a pain it was doing that quest step myself, so I would try to help people out when I got the chance. Got some nice messages from doing that a few times.
