#1662: Jack and Jill explain

$Jill and Jack / began to frack. / The oil boosts their town. / But fractures make / the bedrock shake / and Jack came tumbling down.$

[Megan is watching as the two kids Jill (drawn as Jill) and Jack (with spiky hair) are walking by her. Jack has a pail in his hand.]

Jill: Me and Jack are going up the hill to fetch a pail of water.

[Megan, standing back alone, calls out after them.]

Megan: Okay, have fun!

[Beat panel.]

Megan: …Wait. What the heck is going on with the hydrology around here?
