"Halloween Authenticity"

A Blonde went into a pet shop and asked the owner
if he had any parrots. The owner replied, "Sorry, I
don't have any at the moment."

"Damn and blast!" said the blonde, "I have been invited
to a fancy dress party for the first time in my life, and I
have been told to be as authentic as possible, hence
the need for the parrot." explained the Blonde.

"Well," said the owner, "if you come back here next week,
specifically on Thursday, I am expecting a shipment from
South America and I'll be able to supply you with a parrot,
guaranteed,"

"Damn and blast!" said the blonde, "I can't come on that
day or for some time after."

"Why not?" asked the owner.

"Because that is the day I'm having my leg amputated!"
