(Strip Number 4512, Original Publication Date, 15 July 1985)
Panel 1: We start the week off with Mike asking Lizzie what she's doing digging in the sand in the backyard.
Panel 2: Elizabeth tells Michael that Daddy told her that if she dug the hole deep enough, she'd end up in China.
Panel 3: A flabbergasted Mike tells Lizzie that China is right through the center of the Earth.
Panel 4: When Lizzie tells him "I got all day," Mike is still gobsmacked.
Summary: Given that the big barbecue wherein Connie announces her and Lawrence's temporary departure is coming up, I'd call this the calm before the storm.
