What was the cartoon characters name that said will never

You're likely thinking of Bugs Bunny, the famous rabbit from Warner Bros. cartoons. He is known for his catchphrase, "Eh, what's up, doc?" and frequently uses the phrase "Of course you realize this means war!"

However, Bugs Bunny does not have a catchphrase that includes "will never." Do you remember any other details about the character or cartoon? It might help me figure out who you are thinking of.
