"Movie" idea--yes, its just "Movie"

An awesome comedy bit I thought of today, ("awesome" according to me):

A second grade class is putting on a photography exhibition for their school, and an adult male photographer who thinks he is THE most important critic/shooter in existence attends as if it's a professional exhibition. He walks around, (all dressed in black, preferably gaudy facial hair and black rimmed glasses,) and openly criticizes every picture, commenting on style, lighting, etc...He makes sure to do it around the child that took it, until there is a room full of crying kids and parental glares. Finally he tells the teacher something like, "How dare you advertise these amateurs as photographers, you should be ashamed!"

(Also, when the photographer sees the initial email or post informing people about the show, he makes some caddy remark to himself like, "These will probably suck.")
