If you see a friend's status with a link that says "most people can not watch this video more than 25 seconds!!! I dare you to watch more than 30 seconds from this video!" DO NOT click on it, it's a virus/ hack.
Link has ads5.canoe.ca at the end.
It could be a status update with the link or it could show up as your friend liking the link, either way it's a virus folks, don't click on it.
