Chopping broccoli...I mean onions

There's a lady I know
If I didn't know her
She'd be the lady I didn't know.

And my lady, she went downtown
She bought some broccoli
She brought it home.

She's chopping broccoli
Chopping broccoli
Chopping broccoli
Chopping broccoli

She's chopping broccoli
She's chopping broccoli
She's chop.. ooh!
She's chopping broccola-ah-ie!
