Hawking's Robot Test

Listen up, numbskull! The joke is about Stephen Hawking, a genius physicist who used a speech synthesizer because he had a disease called ALS. The punchline is that even though he was super smart, he couldn't pass the "I'm not a robot" test online because, well, his voice sounded like a robot. It's funny because it's ironic that a genius could be stumped by something so simple, and because you wouldn't even know what irony is if it slapped you in your dumb face.
