Rules of Engagement: Season 6 (2011 - 2012)

In the sixth-season premiere, Russell wants out of his marriage with Liz; and Jeff tries to get Audrey to talk dirty.

Russell's dad meets Liz, and Russell goes to great lengths to win his dad's approval; and Jeff insensitively places his guys' feelings before Audrey's.

After having throat surgery, Audrey is temporarily unable to speak, much to Jeff's delight. However, when Audrey is unable to give the eulogy at her aunt's funeral, Jeff is forced to step in. He tells a sweet anecdote at the service, but they discover afterwards that his story was about the wrong aunt. Russell insists that Timmy must fire an employee, but Timmy only agrees to do so on the condition that he is given a pay rise. Adam is dismayed to realise that he gets special treatment because of his good looks and he becomes determined to prove that he is more than just a pretty face.

The group take a trip to Vermont to admire the autumn foliage, but Audrey and Adam get into an embarrassing situation during a hike after an accident with some poison ivy. Timmy attempts to console Liz about Russell's negative attitude towards her, but his actions are misinterpreted. Jeff tries to make Jen look like the culprit when he has a mishap with the hotel's computer.

Jeff has been ringing Audrey using an app on his phone that automatically puts his calls through to her voicemail, so that he can avoid talking to her while getting the credit for trying to stay in touch. When Timmy accidentally reveals what he's been up to, Audrey uses her voicemail to get even with Jeff. Russell is trying to put more effort into his marriage, while Liz continues to pursue Timmy after their misunderstanding in Vermont. Things come to a head when Liz tricks Timmy into a secret rendezvous at Russell's office. Meanwhile, Adam befriends a clothing salesman after his friends ridicule him for his progressive fashion choices.

Jeff has high cholesterol and Audrey encourages him to eat healthier food, but he sneaks around with Brenda to eat junk food; and Russell can't keep up with his college intern at parties.

Audrey orders an arm chair that she won't admit she hates and that Jeff pretends to love; and Russell accuses Timmy of sexual harassment.

Jeff plans a romantic scavenger hunt for Audrey; Adam leads Russell to believe that Jen has a sex tape.

Audrey thinks her maid needs money to fix her limp and asks some neighbors to contribute, but she then learns that she totally misunderstood why the woman wants the money.
