Bluff your way out of it

The tall dark fellow addresses you thusly: "Thath thee any Knaves of Swords?"

You glance at your hand of blank cards and say, "Certainly. Of course I do. Why wouldn't I?"

There is a pause, which was probably supposed to be filled by you giving the man the card he requires.

"Um," says the Manager at last, "Are you going to give him the card he requires or not?"

You glance at your hand of blank cards and say, "Certainly. Of course I will. Why wouldn't I?"

You begin imperceptably scooting your chair away from the table as you buy yourself more time.

"Hey, uh, Mr. Cape, do you have any Blank cards of Blanks?"

The man looks at you like you grew him another head. "Thou art so... odd." he says.

You know you're running out of time. The manager is already stroking his trigger in a menacing way. But, a few more feet and you'll be within Grenading range. You must hold out!
