But how did you happen to know the money was there?

I just had to ask how they happened to know one another.

Remember what it is, but don't ask me how I happened to know.

I happen to know that you're not getting new help in here.

"You didn't happen to know if they got her social security number?"

And I happen to know someone who is very good.

Do you happen to know where I'm likely to find him?

"Do you happen to know where I might find my wife?"

Do you happen to know where we might find her?

And she happened to know that her body was good.
