Once I was doing Tehnakai Temple, and the second monk in my party was taking damage far too much. I kindly said "it will be better if you stay away from the melee and hang a bit further back".
To which he replied:
"STFU I AM NOT NOOB. I AM HEALING TOUCH THE MELEE SO THEY DONT DIE, IDIOT."
....man, I wish I had a screenie of that.
