You would never consider allowing any fluid even remotely resembling urine to touch your beloved TURNTABLES. That would risk breaking them, and a world without the gift of your godly science just doesn't sound like a place you want any part of. While you're at it, you might as well wipe out human civilization with a meteor or something ridiculous like that which will probably never happen.
That sort of thing only happens in stupid idiot movies for stupid idiots.
