This might be the most random thing I've ever seen. Joe Montana made an appearance on a Spanish language television program, and this is the resulting video. The host of the show is speaking in Spanish, and Joe is answering back in English with a Spanish translation over top. I don't know if Joe had the questions written in front of him, or if he understands Spanish but does not speak it as well.
Whatever the case, it is entirely random. If you speak Spanish, feel free to offer up any interesting translations you see in the video. I tried to learn Spanish, and it just never took. I've never been good with foreign languages.
