Help! Pen plus two year old times tv equals yikes!?

Question:My question is exactly as you see it above! My two year old managed to find a ball point pen from somewhere (still no clue, or where he's hidden it now!) and while I was cleaning up the house proceeded to write on our tv monitor with it before I caught him! Please help me figure out how to get it off before his dad gets home; Steve is very overprotective of his electronics! Thank you!

Answers:
I would first try windex and if that doesn't work try rubbing alcohol.
