What must I do?

Something I must do.

What must I do?

...because I must do it.

I must test it. Where do you do that?

Is there anything I must do?

Well, then, what must I do?

Master, must I do all this?

It's something I must do, because...

You must do as I say. You must kill Tao Li.

But you must do as I say.

I must do this. It's simple arithmetics.

They do look tired, I must say.

I don't know. One must do something.

There must be something I can do.

No. I'm afraid I have work that I must do.

I would still do what I believe must be done.

I must ask you to do just that.

Must take good care of yourself. I do.

I must be in my dotage, but I do believe you.

I'm very sorry, doctor, but I must do it.

I know, dear. You must do whatever you wish.

I must do some shopping in the market tomorrow.

Yes, his slave! Whatever he commands, I must do!

No, it's too late. There's something I must do.

Tell me what I must do in his name.

There must be something I can do for you.

We must do it, and you know it as well as I do.

I must ask you now, do you stop or do you carry on?

Must thing I do right handed. I didn't liked being left handed.

Oh, thank you so much. I do appreciate it. I must hurry.

If you won't, you must do what I tell you.

I must be out of my mind to do this.

And if you must know, I do not like boxing.

We must fight. I do have friends at the Bar.

I must now do a little insisting of my own.

I know how you must feel, but there was nothing I could do.

I must go where I can do the most good for my country.

I must be very stupid, but I do not understand any of this.

I don't know how you do it, I must say. Most praiseworthy effort, I think.

And now that I'm Count Bezukhov, I feel I must do something about it.

But I couldn't let you do that, sir. I must first ask Mr. Sanders.

We should do so sincerely, earnestly and, I must say, effectively.

You must need a drink badly. I do not! Take it.

But if you do, you must tell the truth. I promise.
