Army Navy

I don’t understand the Army-Navy game.
They say it’s a rivalry, but shouldn’t they be learning to work together?
You know, because they should be working together to defend our country and kill our enemies.
And why are they playing football? Or basketball? Or any other sport?
Why aren’t they learning to shoot guns, fire mortars, sail ships, fire torpedoes, and fly planes?
When was the last time we had to defend our country with a football or a basketball?
Take off the football helmet, pick up a gun, and put on a combat helmet.
And fight the real enemy!
