I'm guessing Shel doesn't get a choice to say what's on his mind. I hope you keep posty-notes Shel! Write down what you might have said if you really could.
Then write a book called something like "Sheldon's What I Would Have Said" and include all the stories. Seriously. It's not a bad idea. If you need an FA section I have a few stories as well.

In fact, there is a well of great stories right here in the Cellar.
We need a book.
