Haha I'm playing Mass Effect 2 at the moment, and this fucking hilarious npc conversation took place so I stood there and listened.
When you get to Illium, in the Eternity Lounge there's a Turian and a Quarian sitting and having a chat about the Quarians love life. The Turian obviously likes her, and he keeps saying
things, hinting at her, but she doesn't notice.
Then, towards the end of the conversation, she says "Anyway, I did get the nerve stimulation program built into my suit."
and the Turian says "Yeah, we should watch this movie. . .what?"
and the Quarian says "Yeah, do you want me to show you?"
and then she goes to press somewhere on the suit, but before she does, she says "Ugh, this is a private conversation, human, get lost"
It is easily one of the funniest things I have heard playing Mass Effect 2. Also the Krogan talking about how Asari are too soft to hold when having interspecies sex.
