I like telling people those links...
During Lacrosse last year we would have to wait for pratice to start, so we would go to the library and tell people to go to those sites that have a strange/embaressing video and won't let you close the site. There was one (I won't say because I don't want to be banned) that had a video of 3 guys doing "things" and when you tried to exit, it said, "Looks like your screwed now!" It was hilarious watching people freak out trying to close it before the librarian came over.
