This reminds me of the late, great Bernard Manning's famous joke about the couple from Harrogate spending their first vacation at their timeshare in Marbella. Edith is preparing dinner and discovers to her horror that she forget to bring the gravy powder.
Ernie says - "Don't fret thasel' Chuckie, I hear there's some folk from Bingley in th' flat downstairs, they'll be bound to have, I'll go see, happen I can borrow some".
So Ernie plods down the stairs and knocks on the door.
When George opens the door, Ernie flashes his best smile and says
"Hasstha any Bisto?"
George takes one look and says "Pi$$ off, ya Spanish twit!!"
