JOKE: A bosun mate and a gunny sergeant were sitting arguing

A bosun mate and a gunny sergeant were sitting on the fantail one day arguing over which was the superior service.
After a swig of coffee the Marine says, 'Well, we had Iwo Jima.'

Arching his eyebrows, the Sailor replies, 'We had the Battle of Midway.

'Not entirely true', responded the Marine. 'Some of those pilots were Marines, in fact, Henderson Field on Guadalcanal was named after a Marine pilot killed at the Battle of Midway.'

The Sailor responds, 'Point taken.'

The Marine then says, 'We Marines were born at Tunn Tavern!'

The sailor, nodding agreement, says, 'But we had John Paul Jones.'

The argument continued until the old sarge comes up with what he thinks will end the discussion. With a flourish of finality he says...... 'The Marines invented sex!'

The bosun replies, 'That is true, but it was Sailors who introduced it to the ladies.'
