Johnson’s sack

Of all the houses on the block, kids love to visit Old Man Johnson’s house on Halloween.
The door opens, Johnson steps out with a large burlap sack, and the kids shout “TRICK OR TREAT!”
“Here,” growls Johnson, and he throws the sack at the kids’ feet.
It’s the possums that he’s caught in his traps. Live or dead, but often quite bloody.
“Possums are good eatin!” the old man says.
Kids toilet paper the trees in his yard a lot.
Johnson rolls the toilet paper back up and keeps it.
“Save me a trip to the store,” he chuckles.
