In that way, rage comics are not like the average viral YouTube video. They are more like a Bob Newhart sketch: the laughs come not from replaying the public foolishness of some stranger, but from watching the awkward reaction of the observer, who almost always appears as a character in the strip. Like Garry Trudeau?s Doonesbury strips, there is usually a punch line after the punch line in which the author reacts to the situation. But where Doonesbury characters typically react with wisecracking aplomb, rage comic characters respond with ? well, rage.
