Whats a good picture?

What makes a good picture? I am still trying to figure that out but this is what ran across my mind when I found this photo: Technically good- ya. Is there a moment- ya. Composed well- sure. Focused- ok. All those things are important to creating a good photograph, but when I found this photo from two years ago it made me stop and laugh- out loud. Its a photo that brings out an emotion, this one happens to be funny, but a photo that makes someone connect with and feel what you felt taking the photo is what I think truly makes a good photo.
