Panel 1: Superman has just finished a battle with Metallo, and is tidying up the area in a leisurely fashion. A small transmitter in the collar of his suit buzzes to life.
Transmitter: SUPERMAN! SUPERMAN!
Panel 2: Superman, still tidying up the debris, taps the transmitter. He's calm.
Superman: WHATCHA NEED, GENERAL?
Transmitter: SUPERMAN, THERE'S A PROBLEM WITH THE HUBBLE TELESCOPE!
Panel 3: Superman's stopped in his tracks, one hand at his hip, his other hand at his chin, a pensive look on his face.
Superman: SOUNDS SERIOUS.
Transmitter: IT IS! THE FEED'S JUST STATIC, AND THE ONLY THING COMING OUT OF THE CONTACT MIC IS A SORT OF TRICKLING SOUND.
Panel 4: Superman is already speeding through space, and has his mouth open to talk.
Superman: blank speech bubble
Inset Panel: Close up. Superman is quizzical
Inset Panel 2: Same viewpoint, Superman lightly slaps himself on the head as if to reprimand himself, a sheepish grin on his face.
Inset Panel: Superman is startled, bewildered, but we don't see what he's reacting to.
Main panel: Zoom out, and Krypto is relieving himself on the Hubble. Superman is doubled over in laughter.
Superman: empty speech bubble
Transmitter: empty bubble
