This one's dedicated to my brother Peter (Happy Birthday!)
Panels 1 through 6 - Blue sky, green grass. KRYPTO happy-dancing a-la-Snoopy. (reference http://www.snoopn4pnuts.com/index.php?p=product&id=579537&parent=31077 ) Lots of motion or vibration lines at the hindfeet.
Panel 7 - KRYPTO is slowing down his dance, and is looking blankly left.
Panel 8 - Lining up on the left side of the panel: PA KENT holding the steering wheel of his tractor, wires dangling from the center column; MA KENT holding the broken halves of an oversized red dog dish; CLARK holding broken off barn doors. The barn and silo is in the background with the roof caved in. The three are looking angrily at the cause of the localized earthquake. On the right side of the panel, KRYPTO looks at us sheepishly, embarrassed.
CLARK: Why can't you eat your meal quietly and calmly like any other normal dog?
