Reference to an off-panel Fritz, one of the Katzenjammer Kids.

Ann: Change of plans, Fritz. I need somebody to pull–

Fritz: Sorry to interrupt, ma’am, but the roof attack…

It didn’t take out the helicopter. It blew up the anti-aircraft guns.

Ann: What! Then we’re under air assault!

Fritz: Must be! But we can’t understand it…

…there’s nothing on radar!
