No apologies needed. I really would like to see the stream of youtube clips you were watching that led you to that though.
I too have had some totally innocent youtube sessions end up in the oddest of viewings. You start off watching a video of a young player we are linked with. Next thing you know you are watching a pre arranged brawl between CSKA and some other Mosckovite team's fans. That links you to a clip of two teenage girls fighting. That leads to clicking a dodgy link that leads to a porn sight.
Moral of the story. We are only 5 clicks away from porn, even if unintended.
