It may not be quite as much of a pop culture magnet as its creative sibling "Family Guy," but this Seth MacFarlane sitcom nonetheless reaches a major milestone with the new episode "300," a reference to the number of episodes it has aired to date. The series is only the 25th scripted primetime show in the history of television to rack up that level of success. As for the story line, the episode sees Roger (voiced by MacFarlane) the alien being haunted by his colorful past.
