(After saving Jeff from a full day of watching all three kids... with Ivey who decided to resist any attempt Jeff made to get her to take a bottle... )
Jeff decided to go out and cut grass. Asa ran after him. Let's flash back to earlier in the season when Jeff tried to crank up his lawn mower only to realize that his battery was dead. Now, Jeff went out with Asa to cut some grass and Asa jumped up on the mower. "I get out here EVERY MORNING and turn your key and pretend to drive your lawn mower!"
Guess Jeff needs to keep his key in another location.
