Being the child that I am (to be honest most blokes are the same) I found the quote in Blackadder, where Doctor Johnson is seeking patronage for his Dictionary from the Prince Regent hits the mark. If you don’t know it I shall repeat it below:
Dr. Johnson: Sir! I hope you are not using the first English dictionary to look up rude words!
Edmund: I wouldn’t be too hopeful. That’s what all the other ones will be used for.
