5. 62, And The Reference To Samarium

Breaking Bad spawned five seasons consisting of 62 episodes over its five year run, which is fitting, when you stop to look at the periodic table, a theme in the show's opening credits. On the periodic table, element 62 is Samarium, which is an injection used to treat pain in cancer patients and kills cancer cells in the treatment of lung cancer, prostate cancer, breast cancer and osteosarcoma. A happy accident, or a poignant message? Knowing Vince Gilligan, we'll go with the latter.
