The characters on Six Feet Under were fascinating to watch, but they often made horrible romantic choices. Even the couples that stood the test of time had their issues. Most of the truly memorable train wrecks didn't last, though. Here's a look back at some of the show's weirdest relationships.

Ruth Fisher and Arthur Martin - Ruth and Arthur's relationship was arguably the most awkward pairing in Six Feet Under history. Apart from the significant age difference, the relationship suffered from a lack of physical intimacy. You can't build a romance on nuzzling and spooning alone; it didn't take long for Ruth to figure that out. Ruth dumped Arthur, and things took a turn for the worse when she suddenly married George Sibley. Arthur showed his jealousy by arguing with George over the origins of the word "formica" and labeling his food. They finally parted ways after the "poo by mail" misunderstanding.

(S03E08) Two words: Jeanne Tripplehorn. Keith's paintball revenge was his finest moment on the show as far as I'm concerned. The Fishers and Diazes played against type and became people of action, if only for a short while. David and Keith settled their differences on the battlefield, Ruth made several uncomfortable moves on Arthur, and Lisa sized up her competition. Petrarch, head lice, and polygamy also came into play.

After placing an order for Army Wives, a new drama about wives living on an Army base, Lifetime has picked up its second drama series, also slated for a 2007 premiere. State of Mind will star Lili Taylor as a therapist whose problems are often much worse than those of her patients. The pilot was written by Amy Bloom, an author and psycho-therapist. Bloom is also a teacher at Yale University and has written for The New York Times, Vogue, Salon, Slate and The Atlantic Monthly. Taylor was last seen in the HBO series Six Feet Under as Lisa, Nate's (dead) first wife. The new series will also feature Lolita Davidovich, Derek Riddell, Levin Chamberlin, Devon Gummersall and Mido Hamada.

These two new pilots are part of an effort on the part of Lifetime's president of entertainment services Susanne Daniels to bring more scripted series back to the network. The network does not currently air any new scripted series in its primetime schedule.
