[Verse 1]
I don't know what it is that you've done to me
But it's caused me to act in such a crazy way
Whatever it is that you do when you do what you're doing
It's a feeling that I want to stay
'cause my heart starts beating triple time
With thoughts of lovin' you on my mind
I can't figure out just what to do
When the cause and cure is you, you

[Chorus]
I get so weak in the knees
I can hardly speak, I lose all control
Then somethin' takes over me
In a daze, your love's so amazing
It's not a phase
I want you to stay with me, by my side
I swallow my pride
Your love is so sweet, it knocks me right off of my feet
Can't explain why your lovin' makes me weak

[Verse 2]
Time after time after time I've tried to fight it
But your love is strong, it keeps on holdin' on
Resistance is down when you're around, pride's fading
In my condition I don't want to be alone
'cause my heart starts beating triple time
With thoughts of lovin' you on my mind
I can't figure out just what to do
When the cause and cure is you, you
[Chorus]
I get so weak in the knees
I can hardly speak, I lose all control
Then somethin' takes over me
In a daze, your love's so amazing
It's not a phase
I want you to stay with me, by my side
I swallow my pride
Your love is so sweet, it knocks me right off of my feet
Can't explain why your lovin' makes me weak

[Bridge]
I've tried hard to fight it
No way can I deny it
Your love's so sweet
It knocks me off my feet

[Chorus]
I get so weak in the knees
I can hardly speak, I lose all control
Then somethin' takes over me
In a daze, your love's so amazing
It's not a phase
I want you to stay with me, by my side
I swallow my pride
Your love is so sweet, it knocks me right off of my feet
Can't explain why your lovin' makes me weak
[Bridge 2]
I get so weak
Blood starts racing through my veins
I get so weak
Boy it's somethin' I can't explain
I get so weak
Somethin' 'bout the way you do the things you're doin'
Knocks me right off of my feet, off my feet
Can't explain why your lovin' makes me weak, I get so

[Chorus]
I get so weak in the knees
I can hardly speak, I lose all control
Then somethin' takes over me
In a daze, your love's so amazing
It's not a phase
I want you to stay with me, by my side
I swallow my pride
Your love is so sweet, it knocks me right off of my feet
Can't explain why your lovin' makes me weak
