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?
