Ralph, like his cast member cousin Wile E. Coyote, uses Acme products...and modern methods, like a helicopter, as a means to an end.
Ralph Wolf resembles his cast mate cousin Wile E. Coyote, except for his bright red nose and the fact he speaks regularly. Wile rarely, if ever, spoke in his feature shorts.
Ralph's cave is shown with animal bones inside, one of the few times anything macabre is even hinted at in these shorts.
The title is a play on the gambling phrase 'Double or Nothing (usually pronounced 'Nuthin', sometimes 'Nuttin').
