X Marks the Spot????

Just when you think your kids are growing up and being more responsible they go and surprise you with this....

Silly me left an orange Sharpie in my bathroom.  I had been walking around with the current grocery ads and circling low prices in the ads with the marker.  I set the Sharpie down on the bathroom counter earlier in the day and forgot about it.  Stupid me!!!! I'm usually more responsible than that and put all pencils, pens, markers, and scissors away from sticky fingers (and by sticky I don't mean sticky in the sense of needing to be washed if you get my drift).  So after supper when I went into the bathroom for something I was surprised although not shocked when I saw orange markings on the counter top (I didn't see the toilet seat or the toilet paper yet).  Mentally kicking myself for leaving the marker there, I of course figured my 3-year-old did it but we asked all of the kids who did it and they all denied it.  The most emphatic denials coming from my 6 year-old (that should have been my first clue).  I took my 3 year-old into the bathroom and asked him why he did it.  He kept denying it and as I looked closer at the counter-top markings I realized that under the scribble was a beautiful number 8.  Bingo!  Giving my 3 year-old a hug I said thanks for telling the truth and called in my 6 year-old whose number 8s I recognize and asked him again why he drew on the counter.  I kid you not..... when I was growing up when we were asked by our parents why we did something our response was always "I don't know" my boys give me this "because I wanted to".  I think I would rather have the "I don't know" suggesting they were out of their minds when they did it versus knowingly doing something wrong.  In the process of discovering that it was my 6 year-old he managed to lie to me 3 times and to Brett once (while I was in the bathroom with my 3 year-old).  So he actually got in more trouble for lying than he did for drawing on the counter-top.  Poor kid!  

Anyways the point of this story is actually to ask for suggestions on how to get permanent marker out of the toilet seat.  I have been able to get it faded somewhat by using Goo Gone and Clorox Bathroom cleaner while scrubbing with a toothbrush.  Any other ideas to get the rest of it off or do I have to live with a toilet seat marked with an X?  (we just bought this seat 2 months ago.... sigh...)
