Seinfeld was a successful comic. The end goal for a lot of comedians is to parlay it into an acting career, which Seinfeld did. Forbes estimates his net worth at $800 million. If that isn't a successful comedic career, than I'm not sure what is.
Actually that's one of the things I like about HN. So easy for a community site to degenerate into a handful of long-running in-jokes, applied to the topic of the day.
