This is trying out a new time-save technique. I've found that no matter what I try, even though Dave has to walk less to meet "Gee I'm Hungry" Weird Ed than if you rang the doorbell, those time savings are negated by the longer upstairs route that requires. Refilling the pool wasn't strictly necessary to avoid the meltdown but time needed to be eaten up between getting sent to the dungeon and Weird Ed going back to his room for the doorbell skip. Biggest problems here: fumbling in the upstairs hallway and sloppy menuing in the garage.
