In this game you will give players the first line of a book (famous or otherwise) and it will be their job to write the second line. Most entertaining line wins. Probably best to set a time limit.
Scoring is even more arbritrary than usual, it's entirely based on what you find entertaining. Decide how you wish based on the number of players.
If you go with famous books you can offer bonus points if they get close to the actually line (or dock points, cos that ain't entertaining).
If you don't feel up to the challenge of deciding on the most entertaining answer, you can leave it to a vote (obviously they can't vote for themselves).
