In this episode Rick uses the cover of a high steel worker named MacDonald and A.J.'s trainer. A.J. goes as a man in need of marriage counseling and a runner in the San Diego Corporate Olympics.
Cecilia Simon (while toasting Rick and A.J.): That's the spirit! To my sons...the dirtiest, sleaziest, low-life detectives in San Diego.
A.J. Simon: Look, Mom, there are two grounds for divorce in the state of California: insanity and irreconcilable differences. They qualify on both counts.
(The boys comment on the Krelmans' divorce history.)
Rick Simon: I don't know why you're being so crabby about this.
A.J. Simon: Because they've broken up three times in the last seven years. Or, is it seven times in the last three years? Do you remember the last they broke up, Rick? Huh? This is going to land us in one of three places: jail, hospital, or...
Rick Simon: ...the trunk of the car we borrowed.
Sandra Piller is the wife of Simon & Simon producer Michael Piller.
The episode title, D-I-V-O-R-C-E, comes from Tammy Wynette's 1968 country music hit single of the same name.
