In hospital parlance "Code Red" means fire. This morning, while I was working out in the cardiac rehab center at the hospital, a voice announced over the PA system, "Code Red, Code Red. Seventh Floor Nurses' Lounge. Microwave." For some reason, that announcement touched everybody's funny bone and the room (patients and nurses alike) burst into laughter. As far as I know, the fire was extinguished before there was any significant damage.
Burnt toast anyone?
