What are some good sentences with the word tentative in it?

What older cartoon used to end sentences with the word 'even'?

• I know this is a long shot, but there used to be an old cartoon character that used to end sentences with the word "even". I wanted to say it was Mr. Magoo, I know it sounds like Mr. Magoo *maybe*, but my wife says it isn't. I use it as a joke around the house, like 'take the dog for a walk, even.' and 'we gotta make supper, even.' but I don't know what it's from, or even what the character used to say, just he spoke like Mr. Magoo, and ending things with an emphasized 'even'. Any help would be appreciated, I know it's a long shot. Thanks,

• Answer:

  The character was Snagglepuss and he often said, "Exit stage right" or "Exit stage left."
