okra: Good GOD!

We have pre-made web responses at work so that we don't have to type the same email over and over. The other day, I was looking through the web responses looking for one to notify an instructor that the book they want to use for their class has gone out of print. I found this one:

Good ________! I regret to inform you that the text used in course _______ is currently out of print.

I'm sure that the person who wrote this intended something like "morning" or "afternoon" to go in the first blank. But, I immediately thought of "GOOD GOD! YOUR BOOK IS OUT OF PRINT!!!". Maybe the instructors would respond sooner if I used that....

Or I could toy with their emotions and write: "Good news! Your book is out of print!".
