Really, really bad science humor
Specifically jokes Einstein might tell if he was a stand up comic, from Andrew Tobias:
“Have you heard the one about God? So He’s at Caesar’s Palace, standing next to the crap table and the croupier says, “But with all due respect, God, Albert Einstein says you don’t play dice with the universe.‘Yeah,’ says God, ‘Wasn’t Al also wrong about the cosmological constant?’”And my favorite:
“So anyway, a neutron walks into a bar. And the bartender says, ‘For you, no charge.’”If you liked these read them all.
