Batman's anatomy

We went to a friends' home for game night last week and had a ball. The kids were thrilled because they got to stay up way past their bedtime . . . Ethan was most excited because there were costumes to dress up in. Yes, he was in heaven. He immediately went for the Batman costume. He came to me later for help undressing because he had to go to the bathroom so I went along to assist with the costume. While he was getting re-dressed, he said, "Mom, Batman has puffy nipples!" I had to laugh out loud. When I settled a little, I was able to explain that those were his chest muscles but good for him for being so observant!
