Script inconsistency: After getting off the phone with J.J.'s doctor, Thelma says that if J.J. isn't careful, his stomach pain "could" become an ulcer. A moment later, Michael says, "I can't believe J.J. HAS a stomach ulcer." There is some obvious confusion on J.J.'s condition.
Before J.J. falls asleep, Michael mentions that their father (James) used to say, "You have to play with the uniform you were issued." But this was never said by James during his time during the first three seasons.
J.J's friend, Cool Breeze, who was featured in the "Wheels" episode, was not mentioned in this episode.
As the episode ends, although he's portraying a drunk, Robert Guillaume stutters trying to say Willona's name while they talk.
When J.J.'s friends arrive at the apartment, they try to wake J.J. up, who's sleeping on the couch. Someone in the audience yells really loud "He's alive!" Watch Willona laugh and then go back to a serious looking face.
After being awakened, Thelma asks J.J. why he and Michael are sleeping on the sofa bed and not in their mother's room. J.J. says that Penny is sleeping in there, but later when Penny is awakened from all the commotion, she comes out of Thelma's room.
When Penny's hiding in the closet, nobody knows she's there, so when her mother decides to check the bedrooms for her, J.J. gladly shows her to prove Penny's not there. He shows Mrs. Gordon Thelma's bedroom and the bathroom, but completely forgets to show her Florida's bedroom and Mrs. Gordon doesn't acknowledge it either.
Goof: When Mrs. Gordon takes Penny back home, they leave her doll at the Evans' apartment, and even when Penny comes back for her dress, she never acknowledges the doll missing.
When Penny insists upon sleeping on the sofa bed with J.J. and Michael, J.J. says she can't because they're both still sleeping on the sofa bed. It's strange that they hadn't begun sharing Florida's room already.
