(At our zoo, we have a dinosaur walk-through area. A mother is pointing out rhinoceroses to her young son.)

Mother: “Look, honey! They have the last living dinosaurs here!”

Me: “Ma’am, they aren’t actually dinosaurs. The dinosaurs that we have on display are replicas on the other side of the park.”

Mother: “But your advertisements said you had dinosaurs here today!”

Me: “We do, but these aren’t dinosaurs. They are rhinoceros. The dinosaurs are on the other side of the park.”

Mother: “But that’s just not true! These are rhino-SAURUSES! I think I know a dinosaur when I see them!”
