littletinyMH once locked his mom out of the house. I don't recall the exact details of the story, but she set me on the counter next to the sliding glass door while she went outside to take care of something really quick. She shut the door behind her and I reached down and flipped the lock, then I began to laugh uncontrollably when she came back to the door and couldn't get in. I wasn't any older than three years old at the time.
