Wait -- I know this.  Mustachioed, mustard, and mustiness.  Oh yeah, must-read, must-see, and must-have.  That's six.  This book says there are 6,000 must words.  I hate to question that number, since folks initially doubted that I'd collected 1,000 one-letter words for One-Letter Words: A Dictionary.
