Green Lantern and Battlestar Galactica

One aspect that I used to get a kick out of with Hal Jordan was how, despite being a superhero and intergalactic peacekeeper, he always seemed to have a tough time keeping his personal life together.  He was a great test pilot, but upon losing that job, he went through a series of occupations such as toy salesman that never really clicked for him.  He didn't have much luck with the ladies either - finally winning the heart of Carol Ferris only to have her become his arch-enemy.
