Missandei: Two translators are on a sinking ship. The first says, "Do you know how to swim?" The second says, "No, but I can shout for help in 19 languages."

Tyrion Lannister: Ah! (weird laugh)

Grey Worm: That is the worst joke I ever heard.

Missandei: You don't even know what a joke is.

Grey Worm: I am soldier all my life. You think I never hear joke?

Tyrion Lannister: You lied to us.

Grey Worm: I make joke.
