Going to the zoo, zoo, zoo. How about you, you, you?

These are some pictures of Jack's first trip to the zoo with his parents and Grandma Marshall. I don't have time to write funny captions under each one right now, so you'll just have to assume something funny is going on in every picture and come up with a caption yourself. If I have time, I will add some. Feel free to suggest some in the comments. I like to make up things that Jack says and does, depending on his facial expressions and the background. Enjoy!
