A Marine and a sailor were in the bar arguing over which was the superior service. After a swig of beer, the Marine said, "We had Iwo Jima."
Arching his eyebrows, the sailor said, "We had the Battle of Midway."
Not entirely true," the Marine said. "Some of those pilots were Marines. Henderson Field on Guadalcanal was named after a Marine pilot killed at the Battle of Midway."

Taken aback, the sai...lor said, "Point taken."

Then the Marine added, "We were born at Tun Tavern."
The sailor replied, "We had John Paul Jones."

The argument continued until the sailor came up with what he thought was the topper: "The Navy invented sex."

The Marine didn't blink.

"Well, that may be true," he said, "but the Marines introduced it to women."
