"Hi, everyone!" Meredith smiled, speaking into a microphone and waving to all the loyal readers of this story. "Welcome to Meredith's tequila-induced Karaoke Dance Party! I'm going to take things down a bit, with one of my personal favourites" She walked over and pressed a button on a nearby stereo, then turned to her new husband Derek, who was sitting on a log, and began to sing to him. "Don't go changin', to try and please me. You've never let me down before, Mmm.." The music sped up a little, then Derek began to sing himself, rolling around in the grass.

"I made it through the wilderness!" he sang, while George played DJ and scratched some turntables. "You know I made it through!" George scratched again. "Didn't know how lost I was until I found you.."

"Yeah!" yelled Izzie, grabbing a microphone while Alex danced behind her, waving his huge tail. "I like big butts and I cannot lie! You other sisters can't deny! When a guy walks in with an itty bitty waist and a round thing in your face you get.." Alex accidently swept Izzie away with his tail, and Mark caught the microphone as it flew throuigh the air.

"Feelings" he sang.

"It's fun to stay at the YMCA!" Addison sang, while the Oceansiders performed the appropriate dance moves behind her. "It's fun to stay at the YMCA.." Addison laughed, tossing the mike to Arizona.

"Do you really want to hurt me?" The peds attending sang, spinning around on her heelys. "Do you really want to make me cry?"

"Ah, ah, ah, ah!" sang Steve and the interns, while Alex stood behind them, holding a microphone up to his stomach so Sydney, languishing inside, could be heard.

"Staying alive, staying alive!" the wannabe Chief Resident panicked.

"Ah, ah, ah, ah!" the interns echoed. Now it was Doctor Bailey's turn.

"Who let the dogs out?"

"Who, who, who?" sang the Mercy Westers, dancing behind her and providing back-up vocals.

"Who let the dogs out?"

"Who, who, who?"

"Shake it up, and dance to the music!" Izzie called, as the mike was returned to her.

"Boom, boom, boom, boom, boom, boom" sang the interns, snapping their fingers.

"Dance to the music!" the crowd sang. "Dance to the music!"

"All we need is a drummer!" sang George.

"For people who only need a beat, yeah!" added Burke.

"Break it down, dream boy!" cried Izzie as Derek busted out an awesome drum solo. She then turned to Mark. "Doctor McSteamy, my man!"

"I'm gonna ask some bottoms.." Mark sang.

"That all the dancers just won't hide" sang Arizona, skating up beside him.

"Take it, Mer!" Izzie called to her friend, who was playing an organ.

"You might like to hear my organ.."

"I said ride, Sally ride!" sang Izzie. Meredith ditched the organ in favor of a duet with Derek, while George returned to his turntables.

"I can't see me loving nobody but you, for all my life!" The newlyweds sang, hand in hand and staring dreamily into each other's eyes.

"Dance to the music!" everybody sang, performing various dance moves.

"Hey Mer, you ain't dancing yet!" Izzie called.

"Dance to the music!"

"Oh yeah!"

"Dance to the music!"

"That's how I like it!"

"Dance to the music!"

"Everybody now!" Izzie yelled.

"Dance to the music! Dance to the music! Dance to the music! Dance to the music!"

"Hey Alex, would you watch your tail next time babe?" said Izzie when the song finished, causing everyone to laugh.

AN: And there it is! I'll start the sequel soon. It'll be called 'Meredith 2: Adventures in Seattle Grace'
