Niles: [to Gunnar] How dare you steal my wife! [to Frasier] Translate!

Frasier: Oh, all right. [to Marta] Senor Crane quiere que preguntas a Gunnar, uh, "Como se atrevez a robar mis zapatos!"

Marta: [to Gunnar] Was fallt Dir ein meine Schuhe zu stehlen?

[Gunnar draws his sword on Niles]

Gunnar: Schweinehund!

[Frasier and Marta jump back in alarm.]

Niles: All right, fine, you want to challenge me? [throws off his jacket and grabs the other sword] En garde!

Frasier: Oh yes, Niles, that's just what we need, a fourth language!

[Gunnar has Niles pinned to the ground with his sword]

Gunnar: Entschuldige Dich sofort! Ich habe nicht Deine Schuhe gestohlen!

Niles: [to Frasier] Is he giving up?

Marta: Piedme perdon! Yo no te robo sus zapatos!

Frasier: He says he wants you to apologize. He didn't steal... your shoes!

Niles: My shoes?!

Frasier: Yes, I'm sorry. Apparently I mistranslated.
