Porpoise?

Today, on the phone, Beryl says:
"My nephew had a stuffed porpoise stuffed animal that he just loved."

Porpoise? As opposed to a dolphin? Could you really tell the difference?

Time flies

Beryl said to me today, "You know what they say, time flies when you're having a good time."

What? As opposed to time flies when you're having fun, I suppose. She claims that I have a different version of this adage because I'm younger. I disagree.
