I've always thought that this was a really sweet proposal, and I'm glad that he said yes. Happy endings are the best!
Can't help but feel it's a bit impersonal, making the whole thing into a show with the idea of putting it on YouTube. What if he said "no"? Well, he couldn't have, not with all the cameras and families and stuff... I mean, the guy practically forced him to say yes. The dude was clearly confused and overcome with emotion and trying to withhold his tears and I just don't feel like this is something that should happen, when proposing.
