I was submitting this joke, and I realized Stephen Hawking couldn't.
It had the reCAPTCHA "I'm not a robot."
Alright listen up buttercup, Explain bear is here. This "joke" implies Stephen Hawking can't check the "I'm not a robot" box on reCAPTCHA because he is physically disabled. You are probably like him, disabled but mentally. I bet you watch Rick and Morty and think you're smart.
