Cacaci's fiancee arrives shortly after Joe jumps, with a homicide detective. No one knew she existed, and Watters wasn't sure of which ex-wife to notify, so how would she have known to be there? Additionally, a homicide detective wouldn't have been assigned to a case without a death, much less a crime.
Joe Cacaci's had five wives:
#2 Katherine (Katie)
#3 Kimberly (deceased)
plus one fiancee, Bettina.
When the detective interviews all of Cacaci's ex-wives, they tell him that Joe was the one who left them. However, in "Tantric Turkey" from the previous season, Diane Grad explains that the reason she invited him for Thanksgiving dinner is because she felt sorry for Joe because his wife had left him.
Melody Cacaci is played in a previous episode, "Viagra-Vated Assault" by Kristan Bauer.
Jeffrey Geiger is seen wearing a wedding ring, even though his wife divorced him years earlier.
The repeat of this episode shown on Discovery Health is edited down from its original length when first aired on CBS. It now doesn't include a scene where after Cacaci's fiancee leaves him when he's stable, he's shown to smile. Cacaci then seems to literally let go and will himself to die, and the monitors show him arresting.
Title: Humpty Dumpty
Humpty Dumpty is a popular children's rhyme in which Humpty Dumpty (usually pictured as an egg) falls off a wall, and cannot be put back together again. The rhyme is below:
"Humpty Dumpty sat on a wall.
Humpty Dumpty had a great fall.
All the king's horses and all the king's men
Couldn't put Humpty together again."
