"Quite Special Parrot" joke

Moshe wants to buy a parrot and goes to his local pet shop to see what they have. The assistant shows him a parrot and explains that this one is really quite special -- it can speak most languages. So Moshe decides to test this out: "Do you speak English?" asks Moshe.

"Yes," replies the parrot.

"Hablas Espanol?" asks Moshe.
"Si," replies the parrot.

"Parlez-vouz Fransais?" asks Moshe.
"Oui," replies the parrot.

"Sprechen sie Deutsch?" asks Moshe.
"Jawohl," replies the parrot.

"Falas Portugues?" asks Moshe.
"Sim," replies the parrot.

Moshe pauses for a while, then asks the parrot,
"Do you speak Yiddish?"

The parrot shrugs its shoulders and says,
"Nu? Vis a nose like dis, vot you tink?"
