Can't Quite Place That Accent

An American is walking down the street in London on a windy day.

A woman is walking down the street toward him when suddenly the wind
blows her dress up, revealing her crotch.  Astonishingly, she is not wearing
panties.

The American, trying to sound as English as possible, says to her, "A
bit airy, isn't it?"

The woman scowls and replies angrily, "What did you expect, feathers?"
