I suspect that if The Big Yin were to tell that joke today, he'd soon be following it with something like, "Cancelled?!!! F###in' "Cancelled"! Nivvurr wurrk again? Ach, f### it onywey. Ah kidnae care less - Ah'm f###in' loaded."

The man himself certainly considers the last phrase an adequate punchline, since he's used it so often. People do laugh.
