Definition of Ignoramus

  Dumble was an ignoramus,
  Mumble was for learning famous.
  Mumble said one day to Dumble:
  'Ignorance should be more humble.
  Not a spark have you of knowledge
  That was got in any college.'
  Dumble said to Mumble:  'Truly
  You're self-satisfied unduly.
  Of things in college I'm denied
  A knowledge -- you of all beside.'
