"Vainglorious dullards! Speak into the chicken! You must talk DIRECTLY INTO THE BEAK!" - Princess Zanda, BLACK PANTHER # 42.

AND not so much a quote, as a conversation, in the same issue, Black Panther # 42:

TONY STARK (IRON MAN): "But this is a new world, T'challa. And you, more than anyone, should recognize the complexity of things."

KING T'CHALLA (BLACK PANTHER): "'Complexity.'"

TONY STARK: "You know what I mean..."

KING T'CHALLA: "Yes, and still you parse your statement -- explain the world to me. You've been to Wakanda many times, but I have never once been invited to your home."

TONY STARK: "--?! What--?"

KING T'CHALLA: "A custom, old as the world itself. A friend welcomes a friend to his house. Washes his feet. The counsel of such a man is well received."

TONY STARK: "Wait--this is about me not inviting you to dinner?"

KING T'CHALLA: "In the years we've known one another, this is the longest conversation we've ever had. This... explanation of the world..."
