One day, Nixon went crazy and started swinging a knife about. Dean
shouted, "Fer chrissake, somebody do something!"

Haldeman immediately ran into the bathroom just off the oval office. He
came back with a can of Barbasol and began squirting it on all the men.

"What are you doing? What this for!?" they screamed.

"To protect you from Nixon cuts," was the rejoinder.
