People who talk about Ricky the Dragging Steamboat or Dick Flair or the Underbaker with any kind of fondness are just nostalgic for a time when they were idiots. Pro wrestling is fucking stupid, okay? Always has been. It's a goddam soap opera for pubescent boys, and everyone knows pubescent boys are considerably less intelligent than dolphins and chimpanzees.
So I guess it makes sense that Hulk Hogan would endorse fantasy fishing. I can only imagine the intellectual heavyweights that appeals to.
