I just want you to know a couple of things.

"I knew a couple of them and they were always happy," he said.

That was something I didn't know a couple of weeks ago.

I know a couple of the men on your list; they are good.

You didn't appear to know a couple of days ago.

I did know a couple of boys in a higher class.

I actually know a couple of people who'd like that.

I know a couple who keep making their 2.5 year old go and stand in a corner when he has done something wrong.

"I know a couple of people who haven't been getting enough sleep myself."

I know a couple of guys who'll be able to tell me.
