I couldn't believe this one thing Ronald Reagan asked when he was wheeled into surgery.

The attempted assassination of Ronald Reagan occurred on March 30, 1981, 69 days into his presidency. While leaving a speaking engagement at the Washington Hilton Hotel in Washington, D.C., President Reagan and three others were shot and wounded by John Hinckley, Jr.

The chief of thoracic surgery, Benjamin L. Aaron, decided to perform a thoracotomy lasting 105 minutes because the bleeding persisted. Ultimately, Reagan lost over half of his blood volume in the emergency room and during surgery.

In the operating room, Reagan removed his oxygen mask to joke, "I hope you are all Republicans." The doctors and nurses laughed, and Giordano, a liberal Democrat, replied, "Today, Mr. President, we are all Republicans."
