Meanwhile, Simon develops a crush on Andy's assistant.

Lew gives Andy and Simon important information about the chicken industry. Meanwhile, in an attempt to impress her new co-workers, Jenny hosts a barbecue at the house, but Andy crashes Jenny's party when he suspects the chicken she is serving could be tainted.
When Lew forgets to warn Andy about an upcoming case, Andy's laptop is stolen before he is able to send in his father-in-law's tax return. The search is on as Andy races against the clock to file the return and expose a credit card scam involving Loretta Crispin. Simon and Wally help Andy investigate the suspects.
Lew enlists Andy's help to investigate a dishonest doctor and his involvement with several of his attractive married patients. Meanwhile, Andy and Jenny lose sleep when their daughter misplaces her favorite toy. Andy and Simon go on a quest to investigate the doctor and locate the missing baby toy.
Andy tries to prove that Lew's old flame, Rita Spaulding, is innocent after she has spent the past 40 years in prison. While trying to solve the crime, Andy runs up against Lew's corrupt former LAPD partner, Mickey Wheeler. Simon helps Andy gather evidence he needs to solve the 40 year old crime.
