Reading about librarians reminds of the time I was back in high school. Sometimes I would team up with my best friend to try and drive the school librarian insane. We both kind of liked her and she kind of liked us but we played little games to see how long it took to get kicked out of the library for a while. If we didn't get kicked out quick enough we would start stacking tables, chairs, books in odd formations or even tying up juniors to the book shelves before leaving. We were usually kicked out quick enough but it made me smile bringing back all of those memories of the playful games we used to do. The again we didn't restrict these types of pranks to the library as we on;y went there when we were bored and wanted to have some fun but the librarian was our favourite as she kind of accepted we were monkeys and harmless and we could be talked to like normal people when we weren't in our silly moods.

PS - I think we put laxatives in the teacher's drinks one day when they had a function in the library..
You should of seen the colour of the lemonade and the look on their faces as we served them those drinks.
