JoJo's Bizarre Adventure - Uncle and nephew at the aquarium.

"Josuke, look at those dolphins."
"Yeah, I'm looking, this is the dolphin aquarium, so that's all we can look at…"
"Look very closely at them. Look at how beautiful they are."
"They look more goofy than anythi-"
"Look at the blowhole in that one. So majestic."
"Uh, ok…"
"Josuke, did you know that dolphins are a widely distributed and diverse group of aquatic mammals? They are an informal grouping within the order Cetacea, excluding whales and porpoises, so to zoologists the grouping is paraphyletic. The dolphins comprise the extant families Delphinidae, Platanistidae, Iniidae , and Pontoporiidae, and the extinct Lipotidae. There are 40 extant species of dolphins. Dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates. Their closest living relatives are the hippopotamuses, having diverged about 40 million years ago."
"Jotaro, I should be at school right now."
"Not today, Josuke. You're learning with me."
