Mel Blanc, speaking as Tweety Bird, didn't say his most popular phrase: "I tawt I taw a putty-tat!", in six cartoons (at-least). In order, they are 01: Snow Business (1953), 02: Heir-Conditioned (1955), (Tweety was in just a 5 to 10 second cameo, as it appears, Tweety was going to be another cat's "dinner to be", he just a one sentence quote). 03: Red Riding Hoodwinked (1955), 04: Tweet and Lovely (1959), 05: The Last Hungry Cat (1961) & 06: The Jet Cage (1962). In the fourth cartoon, "Tweet & Lovely", Tweety called Sylvester, "a peeping Tom cat".
Do you like it, putty?
Tweety: Oh, come now! It can't be *that* bad.
