"May the fourth be with you"

"May the fourth be with you" plays on the phrase in Star Wars "may the Force be with you."

"May the fourth be with you" was popularized by Margaret Thatcher and the United Kingdom's Conservative Party. On May 4, 1979, Margaret Thatcher became the first woman Prime Minister of the U.K. To celebrate, the Tories took out a newspaper ad, which stated, "May The Fourth Be With You, Maggie. Congratulations."
