There ain't gonna be no core.

'There's plenty of boys that will come hankering and groveling around you when you've got an apple and beg the core off of you; but when they've got one, and you beg for the core and remind them how you give them a core one time, they say thank you 'most to death, but there ain't a-going to be no core.'
Mark Twain - Tom Sawyer Abroad.
