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.

Sex and the...carpool lane? That's what TBS is going for with their new microseries, Commuter Confidential, debuting Monday, June 2, during the sanitized Sex and the City at 11 p.m. EST.

But they're not fooling us. It's advertising, not a series, micro or otherwise. The 2-minute pods feature four women who, while trapped in a car together to and from work every day, yap about sex, death, bodily fluids, celebrities, politics, and their experiences with Match.com, all while applying Revlon makeup.

Daisy (Keri Lynn Pratt) is the aspiring artist, fresh out of college and ready to take on the world. Carmen (Idalis DeLeon, pictured) is an attorney who brings home the bacon while her loser hubby sits home and cracks open the brews. Former beauty queen Paula (Dorie Barton) is kvetching over the breakup of her marriage. And Sylvie (Dee Ryan) cares for her aging mom while running a Montessori school and wondering why the hell she ever gave up her investment banking job.
