Can your Duck Speak Spanish?

Audrey has a very talented duck. With only the slightest bit of help it can speak any language imaginable. Up until now I thought that it only spoke "quack" but I was mistaken. I recently had the pleasure of overhearing Audrey discussing this with a Spanish-speaking person we know.

Audrey: "My duck speaks Spanish. Do you want to hear it?"
Lupe: "Sure!"
Duck: "Quack, quack, quack, quack, quack, quack, quack" (to the tune of Old MacDonald)
Lupe: "Oh!"
Audrey: "Can you speak Spanish by quacking?"
Lupe: "Um, no...I don't think so."

Perhaps next we'll get to hear the duck speak French!
