Lyrics:

I can't believe this, man
Maybe I should ask her
You joking?

I already know
I smell the scent in the carpet
I already know
When you walked threw the door
Oh, oh baby
I should have known, should have known, should have known
Oh baby
I already know, oh
Yes, I do, baby
I already know, oh
Yes, I do, baby
When you walked through the door
It was late when you did it
Oh, oh baby
Oh, I should have known you were scammin'
Oh baby
Why'd you do it? Why'd you do it?
Oh baby
I should have known better (Should have known better)
Oh my baby
