I'm curious. It can be a line from your character, one that you said to another player, something another player said to you, something an NPC said to your character, etc.
One of mine I can think of off the top of my head is from Elder Scrolls: Oblivion and is this:
(male)NPC: "I like what I see."
Which wouldn't have been so funny if it weren't for the fact my character was a male as well, (Dark Elf if it matter) although, I HAD designed him very much as a pretty boy.
By all means, share yours, please.
