Poison in It

Captain:—“John, go up-stairs and ask my wife to give you my field-flask; but don’t you drink out of it. I believe there is poison in it.”

John (in the Captain’s rooms):—“Will the gracious Frau kindly give me the Captain’s field-flask?”

Captain’s Wife:—“Which is the one he wants? There are several hanging here.”

John:—“The one which the Captain believes has poison in it.”
