Too much pulling from the back is definitely happening here. Children would definitely cry once they see a face like this. No need to pull of an angry one if it naturally appears like this. Ooops, did I say natural? I meant to say transformed.
These twin brothers have way more chins combined. Those chins can definitely hammer a nail. Of course they would not mind having a pic or two with those reformed faces. Maybe people are crazy to get them as product endorsers.
