Mine is terrible. There is a golden crescent around my bog-hole from where I missed. I don't bother to clean it up, because I discovered that the stench reminds me of the Jorvik Museum in York, and that's just fine with me.
Jesus Fuck! What I really hate is piss stench in the toilet, once it inhabits the place it'll never move.
I used to share a flat with three other people, two of them boys, and they pissed and missed, and no one else but me cleaned the toilet. :s If for no other reason, I was happy to move.
