The Newlyweds Move In

S1, E5: Checking out the place that the kids have rented, the mothers return their deposit and fix up the Hubbards garage apartment for them. After their snooping gets them caught hiding in the kid's shower, they promise not to interfere, but their curiosity gets to them when they see friends arriving for a dinner party. Peeking in the electric garage door windows, they wind up spending the evening lying atop the horizontal door after Jerry opens it for some fresh air.
