5. The Gallaghers (Shameless, Showtime, 2010-Present)

As crappy as some of the other kids to grace our list may have had it, they were at least blessed with parents who (at some point, to some degree) cared about their upbringing. Not the case with Frank Gallagher (William H. Macy), who's perfectly content to sit on his ass drinking, collecting disability checks, and letting his six children raise themselves.

Among his kids, there's one who kills animals (Carl, played by Ethan Cutkosky) and another who earns all his cash by taking other students' tests (Philip, played by Jeremy Allen White). Who knows what the Gallagher crew would do without eldest sibling Fiona (Emmy Rossum), who helps hold the troop together in daddy's mental absence? Come to think of it, who knows what 
we would do without the sexy Emmy Rossum?
