Human Nature

Human Nature by Michael Jackson (Boyz II Men version) is featured in Michael, the eleventh episode of Season Three. It is sung by Mercedes and Sam.

When Mercedes gets a text message from Sam to come to the auditorium to sing, he promises her that after the duet, he would let her go back to Shane and that he would stop pursuing her so desperately. She then starts to walk away, but as she is about to walk out of the auditorium, Sam starts playing the guitar and they end up singing to each other. During the performance, they sing playfully, and on the auditorium stage, there is a screen with big letters with Mercedes's name in flashing lights. After the performance, they share their first kiss.

Lyrics

Mercedes:
Looking out
Across the nighttime
The city winks a sleepless eye
Hear his voice
Shake my window
Sweet seducing sighs

Sam:
Get me out
Into the nighttime
Four walls won't hold me tonight
If this town
Is just an apple
Then let me take a bite

Mercedes:
If they say

Sam and Mercedes:
Why? Why?
Tell 'em that it's human nature
Why, why

Mercedes:
Does he do me that way?
If they say

Sam and Mercedes:
Why? Why?
Tell 'em that it's human nature

Sam:
Why? (Mercedes: Why?) Why?

Mercedes:
Does he do me that way, yeah

Sam:
Reaching out
To touch a stranger

Sam and Mercedes:
Electric eyes are everywhere (Mercedes: Ooh)

Sam:
See that girl?
She knows I'm watching
She likes the way I stare

Mercedes:
If they say

Sam and Mercedes:
Why? Why?
Tell 'em that it's human nature
Why? Oh, why?
Does he do me that way?

Mercedes:
If they say

Sam:
Why? (Mercedes: Why?) Why?

Sam and Mercedes:
Tell 'em that it's human nature

Sam:
Why? (Mercedes: Why?) Oh, why?

Sam and Mercedes:
Does he do me that way?

Mercedes:
I like livin' this way

Sam:
I like lovin' this way

Mercedes:
Oh, why, oh, why
Oh, why, oh, why

Looking out
Across the morning
Where the city's heart begins to beat
Reaching out
I touch his shoulder

Sam and Mercedes:
I'm dreaming of the street

Mercedes:
And they say

Sam:
Why? (Mercedes: Why?) Why? (Mercedes: Why, why, why, why)

Sam and Mercedes:
Tell 'em hat it's human nature
Why? Why?
Does he do me that way?

Sam:
Why? (Mercedes: Dooby-doo-why) Why? (Mercedes: Dooby-doo-why, ooh)
Tell 'em that (with Mercedes:) it's human nature

Sam and Mercedes:
Why?

Sam:
Why?

Sam and Mercedes:
Does he do me that way?

Mercedes:
I like livin' this way

Sam:
I like lovin' this way

Mercedes:
Oh, why, oh, why
Oh, why, oh, why

Sam and Mercedes:
Why? Why?
Tell 'em that it's human nature
Why?

Trivia

Despite Sam saying that he and Mercedes had never gotten a chance to perform a duet with each other, they had sung Summer Nights together in Yes/No. This could be justified by the fact that they weren't singing together at the same place though (one at the bleachers and the other at the canteen), hence they couldn't have acknowledged it as a 'duet'. Summer Nights could also be classified as a group number, because several other students sing solo lines.
This performance marks the second time a character has their name in lights, the first being Kurt in Laryngitis (during Rose's Turn).
