middle of the pan type of girl

It's a joke with some people I work with that when they see a piece of ______ taken out of the middle of the pan- they know it was ME who did it.

So, when Gracie made chocolate chip cookie bars today and asked if I wanted one, my answer was, "YES!  But, I want one out of the middle."  
Apparently, she didn't hear that part of my response and expected me to get my own.  This is what I saw when I got to the pan to get my own cookie bar...

 I just had to laugh...
