It's like the Woody Allen joke about Nixon.

He wakes up 200 years into the future, and after acclimating to his new environment he's asked to tell a group of scientists about the 20th century - of which most information had been lost.

They ask him about Nixon.

"We believe this man was once the president; but that he did something so awful, all traces of his tenure were wiped off the history books."

"This is true; he was the president," Allen replies. "Every time he left the White House, the Secret Service counted the silverware."
