What's in a name?

This afternoon, Ben and I were outside and stopped to talk to some neighbors that we had not met before. They were a sweet, older couple and were so kind to both of us.

A few minutes into visiting, they turned to Ben and asked, "And what is your name?"

With a completely straight face, our youngest looked right at them and replied, "Green Panther."

Honestly, who is this child's mother?
