Lyrics

Who's that girl standing up against the wall?
The one with the hair, yeah I guess she's kind of tall
Or she might be kind of short, I can't really tell from here
But from scoping out the room, there is one thing that's clear

Everybody wants to get down
Everybody wants to get down
Everybody wants to get down
Except Margaret (Except Margaret)
Everybody wants to get down
Everybody wants to get down
Everybody wants to get down
Except Margaret (Except Margaret, right, yeah)

Everybody stared at her, they asked her what was wrong
She's trying to pretend that she didn't like this song
She wasn't like the rest of them, she knew that this was true
She couldn't just get up and leave so what's a girl to do?

Everybody wants to get down
Everybody wants to get down
Everybody wants to get down
Except Margaret (Except for, right)
Everybody wants to get down
Everybody wants to get down
Everybody wants to get down
Except (Except for)

Margaret had a secret nobody ever knew
The reason why she wouldn't do the Electric Boogaloo
But then one day i asked her, and much to my surprise
She never said, but showed me instead, and now I know the reason why

Everybody wants to get down
Everybody wants to get down
Everybody wants to get down
Everybody wants to get down
Everybody wants to get down
Everybody wants to get down
With the exception of Margaret

Notes

The "Electric Boogaloo" is a reference to Breakin' 2: Electric Boogaloo.

The words to the incoherent mumbling in the middle are "and not even dance with anyone and how come you'd god dammit why do you even come to a freaking dance place and just just stand there and not dance and nobody's dancing and just guh doesn't"
