I think I need to watch my mouth...

I don't know about anyone else but my kids pick up everything that Christopher and I say!  Every little expressive word that I have in my vocabulary are starting to pop up in my children's.  For example, walking out of the church on Wednesday my son exclaimed "Its Freakin' cold out here."  Funny, oh yes.  Appropriate for a three year old, NO.  The other day they were quoting my husband.  "Watch out you moron!"  This was used when they were pretending to drive!   I can't seem to stop myself either.  And these aren't the worst of the words if you know what I mean.  

I plead for your help.  Share a story where your child has repeated a not so nice word, or tell me how to cut them out of my vocab!  I would rather hear the stories though...
