Welcome to Matt's Army Humor!
An F-117 was flying escort with a B-52 and generally making a nuisance of himself by flying rolls around the lumbering old bomber. The message for the B-52 crew was, "Anything you can do, I can do better."
Not to be outdone, the bomber pilot announced that he would rise to the challenge. The B-52 continued its flight, straight and level, however. Perplexed, the fighter pilot asked, "So? What did you do?"
"We just shut down two engines."
