Heartwarming / Rules of Engagement

• In "Snoozin' For A Brusin'", there's a two little connected details you would miss if you blinked in two scenes. When Jeff walks in after brushing his teeth to go to bed, he says to Audrey he's sick of all these sexy vampire shows taking up TV. Later when Adam is watching TV with Jennifer, he says he really loves these sexy vampire shows, but adds don't tell Jeff, he doesn't like those. He says it like a little kid who doesn't want his bigger brother to know, which is really sweet.
• In "The Birthday Deal", Jeff's toast after Audrey gets mad at him because of his overt cheapness.
  Jeff: Excuse me everyone, I'd like to make a toast. I'd like to thank you all for coming to my party but more importantly I would like to take a moment to thank Audrey for all of her hard work in putting it together. It's much nicer and classier than I deserve, but then again, so is she.
• In "Unpleasant Surprises" Jeff gives this nice bit:
  "I'll never admit this to his face, but Adam's a good friend."
  • Jeff, Russell and Timmy then throw the bachelor party for Adam in the train that's stopped on the tracks and it's a success.
• The final episode is full of them. Jeff and Audrey have their kid via their surrogate and Jeff promises to his new child that he'll be the best dad he can, Adam and Jennifer finally get married and Russell and Timmy have a green card marriage since Russell didn't file the paperwork for Timmy's work visa properly and didn't want him kicked out. Then it turns out that Audrey's pregnant too, which is a surprise since it was supposedly medically impossible for Audrey to get pregnant. Also, Jeff hugging everyone in the cast as they slowly pan the camera outside of the window in the final shot of all the characters.
