What's the funniest/best catchphrase from a cartoon character?

What’s up doc? I tawt I taw a puddy cat & Yabba Dabba Doo…...being just three splendid examples of this craft. I must admit, my allegiance lies with this little fella. How about you & yours….eh? Admittedly it doesn’t necessarily have to be a catchphrase. Just something the particular character is well known for saying.
