Strong Libs

Summary

Have you ever played Mad Libs? If so this is the same basic concept, except that you only have a few you can do and once you do them it gets boring. For the few deprived souls out there who haven't played Mad Libs basically there is a story with blanks placed strategically all over it where words should be. Now the blanks often have words under them, like noun or adjective and these tell you what kind of words you can put there. It's pretty fun and it gives you a chance to widen your vocabulary a bit.
