Clo. Where you shall be the quicker if while here

You can keep silence.

Fife. I may whistle, then?

Which by the virtue of my name I do,

And also as a reasonable test

Of waking sanity—

Clo. Well, whistle then;

And for another reason you forgot,

That while you whistle, you can chatter not.

Only remember—if you quit this pass—
