Normally, as in, almost never, as in maybe 3 times ever I've watched a movie on YouTube and usually never the full length. I will watch a clip and cut out, mostly because I've seen the movie already.
Actually, I've watched Pineapple Express already. While searching for gameplay videos I ran into this vid. It's a completely free legit version of Pineapple Express on YouTube. The downside I believe is that it contains commercials. I remember really liking this movie when I first watched it so I thought I'd share my random stumblings with you guys.
So there it is. I know you guys have alternatives but, there it is anyway.
