Just wondering if there is sarcasm in that quote?? Im in a fish biology class right now and the prof just got through explaining that the adipose fin has very little impact on the fish. There is a thought that it has to do with reproduction... bigger is better. If you could elaborate I would appreciate learning more about it.

thanks

There was more than a touch of sarcasm in Vedder's comment.
