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?
"Links" to these videos?..........I don't know of any forums that allow video uploads to the forum site, so you must have posted them somewhere on "social media"
