This is a pretty good story, with a couple of highlights. One is Blanche,flopping around in the seat on the plane. So funny, it reminds you of how great an actress Rue McClanahan was on the show.
The second is the appearance of Lou the plumber, who shows up next season, as Mr. HaHa, which is one of the funniest scenes of the entire series. Here he's a funny plumber who gets the door slammed on him by Dorothy. The whole plumbing story with Dorothy and Rose is a good one and Sophia's comment about an old lady's dream and a toilet in the living room is really funny.
