A sailor and a Marine were in a bar drinking beer and arguing about which was the better service.
As the argument progressed, the Marine said, “We have Iwo Jima!”
The Sailor stated, “We have the Battle of Midway!”
The Marine corrected him and pointed out, “Not exactly, there were a lot of Marines who fought and lost their lives in that battle.” The Sailor conceded to the Marine that the Navy could not have won the battle without the help of the Marines.
Out of desperation, the sailor blurted out, “The Navy invented sex!”
With a big grin, the Marine retorted, “Maybe you did, but it was the Marines who introduced it to women!”
