That guy

Peter Griffin, a man with brown hair and glasses, looks surprised with his mouth open, then the scene cuts to a man with a mustache and earring looking shocked, followed by Brian the dog with a wide-eyed expression, then a man with blonde hair and a cap looking concerned, then a wall with two blank panels, and finally a green figure on a unicycle bursting through the wall from the outside. The setting appears to be a courtroom or public meeting room.
