Lady and the Tramp is that movie with the spaghetti. Per the proffered selection of Youtube shorts, people also remember the Siamese cats. According to the Wikipedia summary, they're the villains. Also, the movie's plot sounds like everything wrong with Disney in the Fifties, but that can't be news to anyone who hasn't been catatonic since before Steamboat Willie. (Ooh, bed sores!) It turns out that it was a technical achievement, though, the first animated movie made with CinemaScope, which is a significant part of why the movie is so well loved today. The plot might be insensitive, sentimental, and shallow, but the whole thing is gorgeous. Gorgeous is what CinemaScope is all about!
