one thing you should note, the asparagus piss smell is only detectable by people with a certain gene
similar to the "soap taste" of cilantro
it's around 50/50, so there's a chance the would-be piss smeller won't detect it
apart from that i dunno, i'm sure there's some things
i once put some "rum extract" in my coffee and my piss was dark brown & smelledf weird, i thought it was blood
