Trick or Treat!!!

He heard a thump thump and a scratch scratch and a tap tap. A wicked sounding little voice outside said, "Let me in!"
"No!" he shouted.
There was a pause.
"Let me in!" said the same voice again. The doorknob wiggled.
"No!" he yelled again.
The doorknob wiggled in the wood of the door, then the doorknob popped out of the hole with a grind and a clang. A strange eye, glittery and wet, peered in at him.
More horrid scratching at the door.
"Let me in!" said the voice, sounding deeper and louder.
"Never!" he cried.
The wood of the door began to dimple and buckle down the lower half of the door. He could see long fingernails. He moved to flee, but it was too late.
The door crumpled apart and a thing bounced into the room, knocking over the single electric lamp, creating a crazy cockeyed shadow.
"Trick or Treat!!!" the shape screamed.
Then it pulled off its head and waited for some candy.
