Most hilarious invasion ever?

[Donerail]

North Korea tried to tunnel under the DMZ into the South; the South/UN forces found the tunnel and the large "Down With American Imperialists" banner in it, so the North claimed it was a coal mine. With a banner. And no coal. In a level of bedrock with no coal in it. So North Korea sent people into the tunnel to paint the walls black so that it looked sort of like they were tunneling through coal (even though North Korea, a nation that produces coal, could have just planted actual coal). Funniest invasion ever.
