Welcome to Matt's Army Humor!
While stationed in Washington, D.C., this man used Arlington National Cemetery as a shortcut on his way to give a briefing at Fort Meyer. To his surprise he encountered a roadblock manned by the military police. An MP approached him and said in a stern voice, "Are you supposed to be here?"
Unsure of what to say, he replied," Not yet."
The MP held back a smile and waved him on.
