Billy. The monster. Billy the monster.
Watch out, Billy, as you walk around.
Billy. The monster. Billy the monster.
There's ugly people living underground.
Billy. The monster. Billy the monster.
They'll defile your body and your brain.
Billy. The monster. Billy the monster.
And you will never be the same again.
Billy. The monster. Billy the monster.
Billy did not heed their good advice.
Billy. The monster. Billy the monster.
He went too far and wasn't very nice.
Billy. The monster. Billy the monster.
Billy, who was once like me and you...
Billy. The monster. Billy the monster.
He has now become a monster, too.
