Shifu,
This is Australian humor here. I found anything that Australians can pick up on and turn into a joke they will do, not all but a lot it seems. You will eventually get truth out of your question.
But I have never noticed anything fishy about my fins, or have I had the urge of smelling them, but it is Halloween today, so ya never know. I think this whole thread smells a little fishy. Sushi anyone?
