The Return of John & Sue

It’s nighttime in an empty urban alleyway, complete with Dumpster® brand Dumpster®, rats and other various vermin. It appears to be quiet, or as near to it as this kind of place can get. Suddenly, the rats scamper away, the pigeons take flight and the resident alley cat hides behind the Dumpster®.

BAMPF!..................................THUD!...................

Seemingly out of nowhere fall a man and woman. The woman, who’s hair and dress mark her as a typical suburban housewife, lands somewhat gracefully on the closed plastic lid of the Dumpster®. The man, wearing a button-up shirt and slacks, plops down into a puddle of what he hopes is water.
“See? That wasn’t so bad.” The woman says as she hops down from the Dumpster® , “I told you we would be fine.”
The man gets up slowly “You aren’t soaking wet. Where do you think we are now, Sue?” He begins to limp to the mouth of the alley.
“It can’t be any worse than where we’ve been stuck for the last month.” Sue shudders, “anything’s better than that, John.”
“I wouldn’t be so sure, Sue.” John reaches the mouth of the alley and stops, looking around cautiously. “There are much worse things than being force to listen to The Clash, and be forced to list the reasons why cheesecake is a pie for a month.”
“Well, if there is I don’t want to know abou—"
“Sue! Watch out!” John tackles Sue to the ground. Sue looks around her, eyes wide from fear.
“W-what is it John?”
“In that box! There’s a monster!”
“John, don’t be silly! Can’t you read? It says ‘Free Puppies’.” She gets up, calmly and walks over to a beaten cardboard box.
“Sue! Don’t!” John shouts in a last desperate attempt to keep her away from the box.
“Stop being so dramatic, it’s fine we made— Oof!” Sue trips over the curb, landing flat on her face, just three feet from the box. Suddenly, the alley cat darts out from behind the Dumpster®, rushes out of the alley and leaps toward box, stopping mere inches from it, hissing. The box begins to shake violently until it explodes in a flurry of old cardboard and out flies a giant rat, which runs off down the street, the cat following close behind.
Sue stares, stunned at the strange events taking place before her. Slowly, after rat and cat are gone, she slowly gets up and backs toward John, afraid to take her eyes from where the box once sat. “H-how did you know that was going to happen?” Voice shaking, she desperately clutches John’s arm.
“I didn’t” said John, frozen in place by shock, “I just didn’t want you to bring home another dog.”
