The original airing of this episode was dedicated to the memory of television producer Aron Abrams, who was found dead of a heart attack on Christmas Day, 2010.

Linda sends family friend and contractor Teddy (Larry Murphy) to rescue Bob, who tells him to come back the next day, after the in-laws leave.

The concerned counselor, Mr. Frond, believes they are "kids in crisis" and conducts a home visit, almost immediately threatening to call social services.

As he is making the call, Gloria finds Bob unconscious and breaks through the kitchen wall, then orders Mr. Frond to hang up and never interfere with the family again.

In its original American broadcast, "Crawl Space" was viewed by an estimated 5.066 million viewers and received a 2.5 rating/6% share among adults between the ages of 18 and 49, a drop from the pilot episode.
