《One Thing Two Do》是由加拿大歌手Justin Bieber演唱的一首歌曲，收錄於他的首張錄音室專輯《My Worlds》中。歌詞如下：
One thing two do, two thing two do
Come on, yeah
One thing two do, yeah
Verse 1:
Girl you got me feeling so hot
Trying to keep my hands to myself
But you're like an open flame
No flame could ever extinguish
Pre-Chorus:
I don't care about tomorrow
Don't care about the world spinning around
As long as I got you with me
I'm good to go
Chorus:
So let me do one thing, two things to you
Just you and me, girl you know what I'm about
So let me do one thing, two things to you
Just you and me, yeah
Verse 2:
If you got a boyfriend then that's cool
But girl let me break it down for you
'Cause all I want is to make sweet love
I'll never ever break your heart and run
Pre-Chorus:
I don't care about the other guy
I ain't tryna hurt him or do him wrong
All I want is girl just let me come
And we can roll around and sing a song
Chorus:
So let me do one thing, two things to you
Just you and me, girl you know what I'm about
So let me do one thing, two things to you
Just you and me, yeah
Bridge:
Girl I'm feeling like it's time now
And I ain't tryna play it cool now
So just let me take your hand now
And we can go take a walk now
Chorus: (Repeat)
Outro:
Yeah yeah yeah, let me do one thing, two things to you (x2)
Yeah yeah yeah, let me take your hand now and go (x2)
