You never expect TV shows to actually play out in real life, but when they do, you hope it's a fun episode and not something sad. Unfortunately, we had to see one of the saddest episodes of Futurama — or any show I know of, really — recently.
If you haven't seen it, the episode involves a faithful dog waiting expectantly for his owner to return, not realizing that it's never going to happen. And if that doesn't break your heart, seeing it play out in real life sure will.
