Tick Tock Doc

The general went to the doctor for a physical. Before he began, the doctor asked him the standard questions -- age, height, weight, and then he asked when was the last time the general had sex.

"Oh," he mused, "It was 1945."

"Isn't that a long time to go without sex?" the doctor asked.

"I don't think so. According to your clock it's only 21:13."
