Chekhov’s story

Once upon a time, there was a shaggy dog named Maguffin.
He lived in a doghouse made of unobtanium with two other dogs named Jack and Doyle, whom I will never mention again.
In this doghouse, there was splotlight in each corner, so Maguffin cast four shadows on the walls.
His owner, who kept a loaded rifle by the door, fed him cans of red herring, which he enjoyed very much.
One night, a glowing object appeared in the sky.
Maguffin looked up at it and barked.
Then, the object disappeared, and Maguffin went back into his doghouse to sleep.
