AUTHOR'S NOTE - This is another mad one shot my rather random brain came up with whilst bored one day. I hope you enjoy the results!!
I pushed the Black album by Metallica into the Impala's cassette player and started singing unashamedly along to the Unforgiven, even as Sam groaned loudly and covered his eyes with an overdramatic hand.
"Dean! Honestly! What is your fascination with Metallica already? Don't you ever want to listen to someone like, I don't know, The Backstreet Boys or something?" he asked in frustration.
I slammed on the brakes and stared at my brother in disgust and disbelief.
"Sammy! Dude! Any more talk like that and you're walking!" I told him in horror. "No one can compare to the genius of Metallica, Sammy! No one! Backstreet Boys! Honestly!"
Sammy turned away with a hugely dimpled grin, even as he said - "Okay, Dean! Whatever!"
"Backstreet Boys suck out loud, Sammy! Is that what you listened to at Stanford? No wonder you're a wuss! You need some metal up your ass!" I said, still horrified at my brother's taste in music.
Sammy seemingly couldn't say anything else for laughing, so I let it go - for now - just carried on driving.
The only chance I got to pay Sammy back was when he was finally asleep later that night. He had his eyes firmly shut, mouth slightly open and he looked so peaceful, I almost didn't do what I had planned for him, but the thought of the earlier Backstreet Boys comment still rankled.
I pulled my permanent marker pen from out of my back pocket, and stealthily wrote backwards on my younger brother's forehead - JAMES HETFIELD IS GOD! - before stealthily creeping away to my own bed for the night.
I couldn't stop laughing the following morning when Sam went unsuspecting into the bathroom and his subsequent yell when he saw my message.
Then all went quiet for a time before Sammy came back out, his hair arranged neatly over his newly acquired tatto before he pointed to me ominously.
"I'll get you back for this, Dean Winchester!" he said with a scowl.
I laughed until I cried.
I wasn't laughing the following day when I noticed the message on my left butt cheek.
Sammy had written in his careful handwriting - BACKSTREET BOYS KICK ASS!
I couldn't decide what was worse - having the Bacstreet Boys tattooed onto my left butt cheek or the thought of my baby brother getting me partially naked to do it...
