Annoying faces

Have you ever seen a face that just annoys you? For no real reason, you are just bothered by this person's face. It happens to me with kids a lot. I'll see a picture of a kid with a certain type of face and they just annoy me and I assume they're annoying kids. It's usually kids with an overly large mouth/smile or kids that always have their mouths open. It can happen with adults too though. Has this ever happened to you? Have you ever seen someone and been automatically annoyed? Do you think everybody judges others on little things like this that can't be helped?
