If you want an addicting yet endless supply of japanese videos to watch with english subtitles... might I suggest anime?
You learn about them both in like 4.3 or something but really dude the stuff is addicting. You have american cartoons which are just start a story and finish it in 30 minutes (minus the ads) and include plenty of sexual puns for adults to get and children not to get.
Then there is japanese manga/anime that basically is a continuous story based on concepts established in prior episodes... which is why if you ever try to just jump in and watch the episodes you become lost and confused, and most americans don't like confusion so they put off the cartoons as dumb and stupid when in reality the intricate storyline is just so awesome that I could rant on forever on such a topic. Now I haven't based my life around it, but it really is quite the addicting phenomenon.
If I enticed you into watching anime, some series I would suggest are Bleach, Naruto, Katekyo Hitman Reborn, and soul Eater.
Just as a warning though downloading the subbed anime is techincally illegal, but also very very very very loosely enforced really more so the anime companies go after the people who sub the anime and not the ones who download it.
