In-Between Meal Snakes

Are you in the habit of having a snake between meals? Or eating a snake before bed-time? Over the years of teaching adults English here, one of the more common (and humorous) pronunciation errors I hear a lot is mistaking "snake" for "snack" since that particular "a" sound doesn't occur in Mandarin or Taiwanese. But this afternoon was the first time I found it in writing!  Hmmm... it's almost bedtime. What will I eat tonight first?
