If you're a Flickr user, maybe you know what I'm talking about. You see something interesting in the last four photos posted by everyone. You click on it, and it leads you to something strange and disturbing in someone's photostream.

I just clicked on a nice picture of someone surfing and ended up in someone's photostream looking at someone's injury, including a skin graft the size of a dinner plate. I had no idea skin grafts looked like moldy steak. Feeling woozy now. I'm not linking to it... you really don't want to see it.

I'd best just stick to my own lovable Flickr contacts.
