Humor and Negative Ads

I've been of the opinion that Obama best negative messages have been when he's used humor. I should note that a "negative" message in politics doesn't necissarily mean nasty smear - it's just when you go after the other person instead of tooting your own horn; it can be substantive (though it isn't here really). So more examples of humorous negative attacks would be "it's like they're proud of being ignorant", and how they jumped all over McCain for not being able to remember how many houses he and Cindy own. In all cases I think they work because they're funny, and that's why they stick with you... but then I'm an Obama partisan and in the Daily Show demographic, so my viewpoint is probably skewed.
