Yeah, I assumed that was a reference to Hwii (don't remember him loving bad jokes, but it has been a while). Riker did make the distinction between dolphin and cetaceans (Hwii was a Delphine, and I think Duane wanted him to be a dolphin but wasn't allowed due to the limitations on trek writers back then).
In defeat, malice. In victory, revenge.
