17-year-old Caitlin Gallagher posted a photo of the finished product on her Tumblr page. She says the feat took her four hours and three Sharpie markers to accomplish! After school over for a four-day period, she went into the stall to write as much as she could for about an hour. Each time she concluded for the day, she would lock the door, crawl underneath, and post an “out of order” sign on the door to make sure no one entered the stall before she had finished!
