one of my friends posted a video on facebook from a site called vimeo, another one of my friends "likes" the video but i am afraid to open it, it looks really weird, kinda long with URL's, more then one and a bunch of codes and stuff.

It just doesn't look right but at the same this is a good friend that i haven't seen in a while and would kinda like to check out the video, should I wait to see if anyone else likes it or writes to him about it or open it up? And has anyone else had something like this on their page?
