What do you call a blind dinosaur?

This joke is a playful pun that comes from the movie “Jurassic Park.” The humor is based on the playfulness of language, specifically the way the phrase “Do-you-think-he-saw-us” sounds like the name of a dinosaur, similar to “Tyrannosaurus.” The joke is structured as a question about a blind dinosaur, which sets up the expectation for a scientific or dinosaur-related answer. The punchline subverts this expectation with a name that sounds like a question about the dinosaur’s vision, which is amusing because it combines the concept of a dinosaur with the idea of it being blind and potentially not seeing the person questioning its sight.
