Character mistake: Rob tells the people that are about to get on the elevator "my wife is expecting a baby!" In all the other episodes where "she's expecting a baby" as well... No change in stomach size at all! Not a single sign of pregnancy... (After 12-16 weeks it starts to show that the baby is there.) Even before Richie was born, still flat as a pancake.
