I recall a chemistry class where any student caught not wearing their safety goggles would have to sing "the goggles song" in front of the entire class.

  o/~
  Goggles.
  You love your goggles.
  They will keep.
  Your.
  Eyes.
  From.
  Burning up!
  
  So wear your goggles,
  Upon your eyeballs.
  If you don't,
  You.
  Must.
  Sing! (+repeat ad nauseam) -OR- Stay out!

Sometimes the threat of humiliation works as intended.
