Daffy Stealing Sylvester's Catchphrase

As we all know, Sylvester's iconic catchphrase is "Sufferin' Succotash", an exclamation of surprise (whether good or bad) that he's been using ever since his debut appearance in 1945's Life with Feathers. Well, what some may not know is that Daffy has appropriated the poor putty tat's catchphrase several times. The first instance of Daffy saying this (to my knowledge), Ain't That Ducky was made and released in the same year as Sylvester's first appearance and he's said the phrase sporadically from 1945-1948, before mostly stopping, likely due to Sylvester becoming a more prominent character by 1948. In spite of Sylvester been the main user of this phrase, Daffy is still occasionally credited with this line, even by Warner Bros. themselves (the 404 page on the Warner Bros. Discovery site). Famously, in an episode of Press Your Luck, the contestants are asked who was famous for saying "Sufferin' Succotash" and they all correctly answer Sylvester. However, Peter Tomarken (the host at the time) deems their answers as incorrect, claiming Daffy said the phrase. After the second commercial break, Peter is called by Mel Blanc, who (in character as Sylvester) corrects the host's mistake, stating that Daffy stole the line from Sylvester. I think I may have missed a cartoon or two (I remember him saying this in Tiny Toons as well), but this is what I could find. 0:00 Press Your Luck (6/14/85) 0:36 Ain't That Ducky 0:46 Baby Bottleneck 0:54 Hollywood Daffy 1:09 The Great Piggy Bank Robbery 1:21 The Up-Standing Sitter 1:33 You Were Never Duckier 1:56 Daffy Dilly 2:15 His Bitter Half 2:25 Fiesta Fiasco 2:34 Skyscraper Caper 2:43 Press Your Luck (6/14/85) Daffy Fuck.
