Famous quotes containing the words funny and/or current:
“The funny part of it all is that relatively few people seem to go crazy, relatively few even a little crazy or even a little weird, relatively few, and those few because they have nothing to do that is to say they have nothing to do or they do not do anything that has anything to do with the war only with food and cold and little things like that.”
—Gertrude Stein (1874–1946)
“The English language may hold a more disagreeable combination of words than “The doctor will see you now.” I am willing to concede something to the phrase “Have you anything to say before the current is turned on?””
—Robert Benchley (1889–1945)
