This book is hi-larious

I left her alone in her exersaucer today, while I went into the other room to grab something. I heard a funny noise coming from my office where she was playing, and I peeked around the corner. She was turning the page of this book back and forth, and every time she saw the dog (or maybe the cow?) on one of the pages, she would laugh uproariously. Must have been a really good book. The video shows me sneaking up behind her to catch the laugh. Stick it out and watch the whole video, it's about a minute, and towards the end I've edited a 2nd clip in there where you see her expression change - it's really TOO fantastic.
