The President was awakened one night by an urgent call from the Pentagon.

"Mr. President," said the four-star general, barely to contain himself, "there's good news & bad news."

"Oh, no," muttered the President, "Well, let me have the bad news first."

"The bad news, sir, is that we've been invaded by creatures from another planet."

"Gosh, and the good news?"

"The good news, sir, is that they eat reporters and piss oil."
