[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

'cuz 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

'cuz 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 do-oo-oo-in'

Knocks me right off of my feet (off my feet)

Can't explain why your lovin' makes me weak (I get so)
