'Parenthood' Premiere Gets Emotional - Preview!

By
When it comes to weepy TV, no show even begins to compare with the tears-per-minute ratio Parenthood has honed over its first three tremendous seasons.
And with Haddie headed off to college, Parenthood's queen of crying, Monica Potter, will be giving her tear ducts a workout like never before!
You can get a sneak peek of the sniffles that are forthcoming with a clip from tonight's premiere episode, titled Family Portrait.
Parenthood airs Tuesdays at 10 p.m. on NBC.
