Picking a (plain)Text

Can you help me think of a text to use for my crypto final? What I'd like to do is to use a relatively recognizable text for all the deciphering problems, but I can't think of a good choice. Things like Shakespeare and the bible are out because the language is so old/formal that i'm afraid that it would cause trouble for the students. Someone suggested the theme song from Gilligan's Island. Not sure if I want to do that.

So: can you think of a relatively well-known text written in modern English that I can use for my final exam? (Relatively wholesome and non-controvesial would be a plus.)
