'Rules Of Engagement' 100th Episode Series Finale: Happy Endings And One Surprise (VIDEO)

After seven quiet seasons, "Rules of Engagement" finally reached its series finale on CBS. In doing so, it also achieved a rather impressive feat. The series finale was also the long-running pinch-hitter's 100th episode. In the end, as expected, things wrapped up neatly for the principal characters.

Jeff and Audrey got their daughter, thanks to their surrogate. And finally, Adam and Jennifer got married. Even Russell and Timmy got a happy ending -- or was it? Thanks to Russell, Timmy was about to be deported, so Russell proposed to him and the two got married.

But "Rules" wasn't done yet. As Jeff and Audrey were bonding over the new addition to their family, Audrey had one more piece of news. "You know I’ve been feeling kinda sick lately, so I decided to get checked up," she said. "Jeff, I’m pregnant.”

The AV Club said that it's a little crazy to think "Rules" has been on as long as it has, saying, "Seven seasons is a damned fine run, no matter how you look at it, but it’s a particularly remarkable achievement for 'Rules of Engagement', a series about which ... no one has ever exclaimed, ‘Oh, my God, that is my absolute favorite!’”

Entertainment Weekly gave the show props for its longevity, and relative success considering it never had a consistent time slot on the network. “Not since Fox’s ''Til Death' has a sitcom on-the-bubble pulled off so many narrow escapes," they wrote. "'Rules' still had semi-decent ratings this season ... But as a show ages, its costs tend to rise, which in turn adds more performance pressure.”
