A Marine and a sailor were sitting in a bar one day arguing over which
was the superior service.

After a swig of beer 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 sailor comes up with what he thinks
will end the discussion. With a flourish of finality he says......
'The Navy invented sex!'

The Marine replies, 'That is true, but it was the Marines who introduced
it to women.'
