A Scout is Clean -- Both in speech and thought.

How important is it to keep your thoughts pure and clean?  Negative influences come from everywhere these days, from movies to video games to magazines.  Disguised as popular or trendy, this filth makes it difficult to keep clean.  Yet it is important that we make the decision within ourselves to be clean and keep our minds out of the gutter.  If you put a drop of clean water into a cup of sewage, the drop of water will not change the sewage -- you still have a cup of sewage.  Yet if you switch it around and put a drop of sewage in a cup of clean water, that single drop changes the cup of clean water into a cup of sewage... Forever.  In other words, if you play in filth, you will come away dirty.  If you even just dabble in dirt, you will still come away dirty.  Make the choice to be clean.
