Let me first say that I have been following this Motivational Poster marathon since it had only three pages, and I have to congratulate all poster authors (and of course others who gave inspiration) for their fantastic ideas. LOVED them all!
I laughed, I drooled, and even went "aaawww" to a few.
I have thought about any posters that I could maybe do, but nothing comes to mind so far.
While I try to create my own poster, let me try to help Kristen. Is the following image what you are looking for? It's from HIM. He doesn't seem to have the pencil *in* his mouth, but it's pretty close.
