It turns out that you don't even have to be born to qualify as one of the undead popping up on the radar of Theresa Caputo, the star of "Long Island Medium" (Sundays, 9 p.m.)  In this exclusive clip, Caputo finds a woman's best friend, Brian, on the other side. Brian, who died in a motorcycle accident almost eight years prior, sends his regards -- and also lets the medium know that he's taking care of the woman's unborn child. Good to know that you can put your dead friends to work as babysitters, at least in the after life.
