Little Johnny was late for class, and when he saw that the door was already closed, he opened it and went into the classroom tentatively. He very quietly shut the door and tiptoed to his seat hoping not to get the teacher after him.
This upset the teacher, who said him, "Johnny, is this how your father would have come in - late and sneaking to his seat? Go out and try it again, and get it right this time!"
So, Little Johnny left the room and shut the door behind him quietly, as he'd come in.
Then a moment later, he flung open the door with a clatter and stomped back into the room with a lit cigarette dangling from his lips. He slammed the door behind him, put his cigarette out on the carpet with his foot and said, "So Honey, didn't expect ME, did ya?"
