HA! It's a riot, isn't it!
I told this story here before, it's back in the archives somewhere, but one of my sons-in-law was a fisherman. Had a gill netter that he sold a couple years back. The family was at our house eating Mrs. Tar Remover's awesome spaghetti. He proceeds to tell us about how a couple days prior, he strung his net out and didn't catch anything but 3 MUDSHARKS.
He could not figure out why I blew a mouth full off spaghetti out onto the carpet, laughing. He had no idea what a mudshark was. I had to explain it to him. :lol
