An anti-Bezhnev joke (but one can substitute brain-dead Biden and timely characters just as well):
During Brezhnev’s visit to England, Prime Minister Thatcher asked the guest, “What is your attitude to Churchill?” “Who is Churchill?” Brezhnev said. Back in the embassy, the Soviet envoy said, “Congratulations, comrade Brezhnev, you’ve put Thatcher in her place. She will not ask stupid questions any more.” “And who is Thatcher?” Brezhnev said.
