Have you ever used someone's toothbrush without telling?
Anyone use someone else's toothbrush for practical reasons (forgot yours) or malicious reasons and put it back without telling that person? Like in the film here or in some other manner. Never anything on my part; always used the finger method if worse came to worse. Though I had a friend ages ago who was mad at his sister and used it on another "opening" that wasn't his mouth and put it back. The time to come clean is now!
