Die, Son
The story of how the Winchesters came to be staking out a store – specifically vacuum cleaners – is a long one, but it does involve the deaths of two gentlemen working a late shift on two separate nights. The local force was completely stumped as to how a vacuum cleaner could strangle two people without any fingerprints or forensic evidence, the newspapers had dubbed the mysterious killer 'The Hoover Phantom', and fears were growing over what household appliance would turn homicidal next.
It was only because Sam had installed a new firewall on Dean's laptop that effectively blocked all the porn – the good kind, anyway – that Dean had used Sam's beloved laptop to surf the web, and stumbled upon the hunt.
And now here they were, at opposite ends of the vacuum cleaner aisle in the darkened, haunted store.
"Sam," Dean whispered, ten minutes into their stakeout and bored.
"What?"
"This job sucks," Dean sniggered. Fourteen minutes later, he piped up again, "Sam?"
Sam tried to massage a cramp out of his leg. "What?"
"This job blows," Dean said, his giggles muffled by his sleeve.
Sam settled in for a long wait, with only Dean's bad puns to pass the time.
THE END
Author's Note: Poor Sam! I wonder why my mind immediately went in this direction... Perhaps it's because I often consider the meaning of life and vacuum cleaners. And I thought when I started this it would turn out to most absolutely definitely 100 words... Ha. Thanks for reading! :)
