Counting Off

I was using my fingers to count the number of children coming to Little Miss's birthday party.  Each child's name was ticked off by pointing to a finger.  Child 1 - index finger.  Child 2 - middle finger.  Child 3 - ring finger.  At this point, Nephew looks at me and, straight-faced, asks me if those are the names of my fingers.  I'm proud of myself for just answering, "No, they are Little Miss's friends coming to her part."  I figured it may be damaging if I laughed at him... like his mother did.
