An extract from one of the 'Winchester Gospels':
Early Morning …
Dean is lazily lying on his motel bed flicking through the usual crappy T.V. channels. Sam is having a most welcomed shower after the long night's hunt shenanigans. Suddenly there's a strange loud metallic bang from outside. "Baby, balls, kids!' runs through Dean's mind as he leaps off the bed to look out of the closed curtained motel window.
An amazing, heart stopping, horrendous sight greets him. The most beautiful magical, nasty, evil unicorn Dean has ever seen, period, jumps down off of Baby after defecating on her now badly dented roof. Then the unspeakable, most unforgivable act happens. With a snorting sneer the unicorn lowers its beautiful, ugly, magical, honed horned head to Baby's flawless, glossy, black paint job. Throwing Dean a honeyed look and evil smirking snort, the unicorn proceeds to horn Baby's delicate, metal flesh with a loud rendering, metal screech from hood to trunk. The magnificent son of a ….. even managed to split poor, helpless Baby's shining metallic flesh in various places with its sharp, sparkly horn.
"Ahhhhhhhhhhhhhh BAAABYYYYY!" Dean takes a deep shaky breath and yells Sammyyy! Then taking a more deeper forceful breath bellows SAMMMMYYY!
Sam upon hearing Dean's girly… I mean manly scream of abject horror with his name being yelled at the top of Dean's lungs. Leaps out of the shower. Grabs the silver knife they had hidden underneath the bathroom sink. Almost slipping on wet treacherous tiles in his haste to rescue… I mean help Dean. Sam with knife gripped tight, exits the bathroom and slides to halt just behind Dean. Dripping wet, butt naked with glistening suds in his hair.
Seeing no immediate danger Sam exclaims "What … what's going on Dean? Dean vehemently with dire menace, controlled rage and forced quietness asks, "How do you gank a unicorn Sammy?" Sammy blankly stares at the back of his head and replies "Huhhhh…..!"
