According to Bill Cosby, he improvised the part when his children sing "Dad is great/Gave us the chocolate cake!"
Much of the material from this performance, including the "Come here" bit and the mother speaking to no one in particular, were reused in Pilot (1984).
A few times in his act, Bill Cosby speaks of the possibility of his son, who was eleven at the time, not living much longer. These were jokes regarding things like his own sisters killing him for not putting the seat down, or his wife making him kill him because of his bad hairdo. However, these were sadly prophetic as his son, Ennis Cosby, would be murdered in 1997 in Los Angeles in a botched robbery.
Louis C.K. has said in interviews that this is his favorite stand up of all time. One of the reasons is because the camera never shows the audience.
When he talks of the other passengers on his flight from Hartford to Vegas waking little Jeffrey up after he fell asleep just before the plane landed, Bill Cosby mentions some of them laughing like Renfield, and then does an impression of the character played by Dwight Frye in Dracula (1931), and his maniacal laugh after being discovered in the hold of the ship. He uses this laugh again when his wife tells him to go upstairs and kill their son for his bad hairdo.
