Youtube question

So after putting a roast in the oven tonight I was surfing YouTube. I was really surprised to see that two videos were there, posted by me (67 dart on alcohol first start).

Here is the weird thing. I have never posted anything to YouTube, and I am fairly certain that the only place I posted those videos are here on fabo (although I cannot find the post here now).

Does anyone have any idea how my videos ended up on YouTube?
FABO hosts photos
FABO does not host videos
Videos that show on FABO are actually linked to FABO from another site.
So you must have uploaded the videos to YouTube, or some similar service, to have the videos ‘shown’ on FABO.
