My friend (who has numerous little speech impediments) used to believe that the line "for which it stands" actually said "for witches stand," and was deeply confused by the importance of witches in the US pledge. She held this belief until she was 16 years old, and finally saw the pledge in print. Unfortunately for her, she made the mistake of telling me, and I make fun of her every time I get the chance!
