Rarely can I 'smell' my pee as I'm taking a leak, and the only time(s) I can remember are when I've eaten asparagus recently, of course. Other than that, I can't recall ever being able to smell it at all unless I'm in at a urinal, in which case it's just smelled like piss.
...THE SMELL OF STALE SWEAT AND SHIT STREAMING THROUGH THE NIGHT.
