He's gruen quhiskers on who's chin again

• Whiskers on his chin again: from the children's folk song "Michael Finnegan", first attested in 1921. The song has a wide variety of verses, including:

  There once was a man named Michael Finnegan,
  He grew whiskers on his chinnegan,
  Shaved them off and they grew in ag'in,
  Poor old Michael Finnegan (ag'in ag'in ag'in)
