I used to build me castles of moisty sand and shells,
And dream they were for princesses who wove me magic spells;
But yesterday along the beach my fairy princess came--
And she's too big for castles--now isn't that a shame!
For the scouting community I offer the a list of scouting jokes from a recent campout my son and I attended. (Eiffel)
