It can be when you're in the Military, believe me. Lots of things are funny that the average person wouldn't consider to be.

I found absolutely nothing strange about that bullet point. Although, he joined the Marines, which means as a member of the Army I have to hate him.

Yes, it's really quite funny. If you're an American & you can't see the humor, try visualizing China invading Iraq instead.

Humor is a way of dealing with psychological inconsistencies. It can be an outlet to deal with the unpleasant. So killing in the military can becomes humorous. 1st year medical school students routinely joke about dead bodies in anatomy lab. Hackers have this site: http://thedailywtf.com/ .

It might be. If these "people" were clowns.
