"Yiddish parrot" joke

Shlomo wants to buy a parrot and goes to a 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 Shlomo decides to test this out.
"Do you speak English?" asks Shlomo.
"Yes," replied the parrot.
"Hablas Espanol?" asks Shlomo.
"Si," replied the parrot.
"Parlez vouz Francais?" asks Shlomo.
"Oui," replied the parrot.
"Sprechen sie Deutsch?" asks Shlomo.
"Ja," replied the parrot.
Shlomo 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?"
