We say goodbye to some small-screen friends

It's irrational to mourn a deceased television character, especially in the real world, where heartbreakingly tragic death and loss happen every day.

But that's what quality TV writing can do: We get so invested in story lines and the characters who bring them to life that we throw reason out the window and cry like babies when one them is killed off. Fans of "The Walking Dead" are still bemoaning the death of T-Dog (IronE Singleton), especially because when he finally displayed some depth and heart in an installment, zombies killed him by the end of that episode.

The 2012 TV season has been especially casualty-filled and bloody, and characters have been expiring by the week. To honor folks like T-Dog and even Lori (Sarah Wayne Callies) -- love her or hate her -- from "The Walking Dead," as well as Lane Pryce (Jared Harris) from "Mad Men" and more, we've compiled an in memoriam of sorts. Think of it as a way to gain closure and say goodbye to our small-screen friends and frenemies.
