Joke about Marines
Can anyone explain the joke about marines and navy in one particular scene?
I don't remember the exact lines. But this is when Jack Nicholson's character goes into washroom full of marines. A marine comments something about sailor getting confused with 13 buttons. To which Jack replies something like, "a marine doesn't have to worry about buttons, he would just lay off his hat". This later sparks a fight between them.
Can someone explain what was that about?
