Karaoke Night

History might remember us as: The Ones Who Failed The Earth; but I prefer our true title: Five Dumb Kids Who Didn't Know Aliens Were Spying On Karaoke Night.
 We were right in the middle of belting out the last chorus of We Are The Champions when suddenly this lime green light filled the room, blinding us.
When we could see again, we weren't in Jason's living room anymore. Because no matter how geeky his folks are, they hadn't yet invested in futuristic biotech walls.
I saw biotech, because there was something fleshy about those chrome walls; namely, all the eyes.
So there we were, freaking out about these eyes in the walls that kept blinking at us, when on of the walls peels away like a ripe banana to let a bunch of alien walrus-roses waddle in.
Have you ever thought about what a walrus and a rose would look like if combined? Don't. It's not pretty.
So, the walroses start barking something at us, with lots of flipper-thorn waving. My friends are freaking out. I'm freaking out. And the wall-eyes are still blinking!
So then Jimmy does something dumb. Really dumb.
He steps forward, stares up at the walrose with the fanciest tusks and petals, and shakily says, "We come in peace."
That throws the walroses into a frenzy, the eyes on the walls start rolling like mad, and the lime green light fills the room again.
We're back in Jason's living room, only the power's gone out.
There's a commotion outside, so we go look.
Guess what? The aliens had a whole fleet of ships, and were attacking the planet.
Turns out, they took us because they misunderstood our karaoke to be a declaration of our status as Earth's Champions, and telling them we come in peace translates to some horribly vile insult toward their entire species and was the absolute best way to start a war, all because they didn't study humankind long enough to actually learn how English and their own language would interact.
It took humankind exactly thirty-seven years to make up for our blunder of a first contact, and my group of friends was banned from ever singing karaoke (and that particular song) ever again.
By the entire galaxy.
