It was raining. Horns were honking. Chuck Jones, the 77-year-old animator, was sitting calmly in a hired black stretch limousine, asking a reporter if he had ever heard about the nefarious doings of the Anti-Destination League. ''You never heard of them?'' he asked, with the hint of a smile. ''Well, they're all over the place, the members of the Anti-Destination League.''

He gestured outside the window at the city's noisiest, wettest traffic jam. ''Their job is to keep you from getting where you're going.'' Where Mr. Jones was going was to a radio studio in Manhattan, to give yet another interview about his new book of memoirs, ''Chuck Amuck: The Life and Times of an Animated Cartoonist.''

''There's no point in cursing all these other drivers,'' he said. ''They're just doing their duty for the league. It helps to know that this traffic is all just part of the conspiracy.'' He turned and looked benignly at a reporter through his aviator glasses. ''I'm surprised that a reporter for The New York Times never heard about the Anti-Destination League.'' Behind the Animated Creatures

Here, then, is the mind that created the Road Runner, Wile E. Coyote and that Gallic skunk Pepe LePew. Mr. Jones has won three Oscars and nine Academy Award nominations for the 300 cartoons and animated features he directed from 1938 to 1986. More than 50 of the Warner Brothers cartoons starred Bugs Bunny and 35 starred Daffy Duck.
