"I'm Chicken"

When someone in the grocery store passed by us today and said to Jackson, "What beautiful blue eyes you have," he replied, "Thank you. I'm Jackson." Except, when he tries to say "Jackson" it sounds more like "Chicken". So the lady said, "Oh, you're a chicken? Well, okay." I just about choked trying not to laugh as we wheeled away with Jack yelling "No! Chicken! I'm Chicken!" at her retreating back.
