shoulder counting seemingly is the newest hottest pickup line on the block though I couldn't tell you that from personal experience I haven't tried it and I don't think anyone would be dumb enough to allow it.
How about a turret and GLaDOS? I can be the turret closed inside a white plastic shell where nobody can see me cry and she can be the disembodied snarky voice in my head, where she exists. haha...
what ? no! a turret and Chell obviously. Glados treats turrets like disposables and turrets never have anything to say about glados so they have effectively nothing going on between one another but the turrets keep saying senpai-notice-me-like things to Chell.
