Don's lying on his couch trying not to expire when Sally calls for him; he picks up to a flurry of complaints about how she hates Pauline, and someone called on Henry's phone saying they couldn't get a flight, so Henry and Betty will be driven back from Buffalo that night, which is weird because Henry is so important, and they never let her know what's going on but they call Bobby at sleepaway camp all the time. "I guess if I was peeing in my pants they might want to say hi?" I think it's more likely they just don't want to have to find a fifth Bobby, so they're keeping him happy.
Sally goes on to complain that Pauline wears a barf-worthy amount of perfume, and she also doesn't believe that Sally's allowed to watch as much TV as she wants during the summer. Even Don raises an eyebrow at that, and tells her to go out and get some fresh air and sun, but Sally tells him it's really hot. And as much as I could listen to Sally bitch about her elders all day and all night, Don does have a point, especially when he adds, "I don't want you to get rickets in that haunted mansion." I'm trying to figure out if the nighttime exterior is more reminiscent of The Munsters or Scooby-Doo, Where Are You?, but either way, HA! Don then hacks into the phone, prompting Sally to ask how he is, and he replies that he has a cold, "but you've made me feel better."
