On porpoise

ME: At the hotel, you can see dolphins swimming from your balcony.

HUBBY: You can see dolphins swimming?

ME: Yeah.

HUBBY: They're called porpoises, by the way.

ME: Maybe we can sit on the balcony and eat tuna and watch the porpoises.

HUBBY: HAHAHAHAHA

ME: What's worse, that I said that or that you're laughing at it?

HUBBY: I think they're both pretty bad.
