Okay, listen up, buttercup. This joke is all about wordplay. "Boo Boo Doo" sounds like the dial-up modem sound, get it? Stephen Hawking used a computer to communicate, and dial-up is old and busted. The joke implies even dead, Hawking's still using his computer, but now it's ancient tech. You probably don't even know what dial-up is, do you?
