On the season three premiere of Breaking Bad, fans met "The Cousins," two Mexican assassins (real-life brothers Luis and Daniel Moncada) who are gunning for methamphetamine kingpin Heisenberg, a.k.a. high school chemistry teacher Walter White (Bryan Cranston).

The love children of Oscar De La Hoya and the Chupacabra? OK, we're probably stretching like Fat Joe in skinny jeans, but that's what happens when we're left to fill in the blanks. So, what do you think their back story is?
