(I think I need a reader-participation subject in an attempt to get the comments section humming -- or at least showing signs of life again. So...)
Someone once told me that Sylvester the Cat is the biggest loser in the cartoon universe, and I couldn't really argue with him. Sylvester appeared in so many different cartoons, including at least three popular series (Tweety, Speedy Gonzales and Hippety Hopper), and not only did he almost always lose, he almost always lost in the most humiliating way possible. And unlike most cartoon villains, who mostly lose when they're asking for it, Sylvester loses even when he's trying to be good. The ending of "A Mouse Divided" has taught generations of children a valuable lesson: don't learn to love those who are different from you, because if you do, you'll be kidnapped by a stork and adopted by mice.
So are there any cartoons where Sylvester actually wins in the end? Maybe "Kitty Kornered," though that cat isn't really fully Sylvester-like except for that one scene where he talks. In general some of the early Sylvester appearances, before his character was fully fleshed out, have him winning: "Catch as Cats Can," where he has the wrong voice but does win out over the Bing Crosby bird, and "Back Alley Oproar" (if you assume he didn't die at the end, which is by no means certain). But from about 1948-9 on, after Sylvester's character was truly established? Hard for me to think of an example. Chuck Jones couldn't even let him win at the end of "Scaredy Cat" without having it all ruined in the very last gag.
So what are some Sylvester victories, however small and fleeting, that come to mind? And is there another cartoon character with a worse track record?
