You surely remember the episode of Futurama where the dog waits for Fry. Did you know it was based on a true story? Yup, they made a movie about it: it's called Hachi, a Dogs Tale. They made two movies, actually. The other one is called ハチ公物語 https://imgur.com/gallery/1c9Ikce
@trinsec The moment I knew my marriage wouldn't last was when she said she thought the movie sucked. I get a little choked up just thinking about it. Almost as much as Grave Of The Fireflies.
