I targeted the lion, clicked on my mesmerize spell, and then I started to type: "I am mezzing the lion for you." I got as far as: "I am " when I suddenly remembered that I had replaced my mesmerize spell with an AoE mesmerize spell. Seeing the high level gypsy enchantress in the camp I knew I was in big trouble. The spell was going to hit her for sure.
Panicked, I tried to move and interrupt the spell. I stabbed at my WASD keys, muttering "oh shit, oh shit, oh shit" under my breath, but nothing happened. Why couldn't I move???
I forgot that I was in typing mode.
The spell fired off and sure enough, the gypsy enchantress didn't like my attempt to mesmerize her. She promptly turned around and charmed me. Next thing I know, my peace loving gnome pulls out a dagger and heads for the guy I was trying to *save*. I swear to god that little gnome looked like a deer caught in headlights when I came after him, but there was nothing either of us could do. Knife flailing like a crazed sushi chef, I chased him down and stabbed him to death.
Dying in Everquest was a pretty horrible experience, so I felt terrible about what happened. I eventually found my victim and he admitted to being VERY confused. He said, "There I was minding my own business, no other players around; suddenly, a strange gnome appears out of nowhere, announces 'I am waaaadddddd', and then he slices me to pieces like some miniature Freddy Krueger!"
NOTE: I posted this story on an Everquest forum and it gained a small following. Four or five years later I was telling a work friend about my experience that day and a guy from a nearby cubicle ran over excitedly and said, "Oh my god. You're waaaadddd?????"
