More pictures I know

Dear Diary,
You won't believe it, but I found more pictures of people I know! A "special friend" and another silly guy appear in this picture.
Now, I know that I have seen this picture somewhere else, without my friends' faces on it, but where? I mean, what kind of silly person would do something like this: putting people's faces on funny and silly pictures? I'd like to know how to do it, but between the hotline and finding new exciting internet acronymns, I don't have the time. I'll update when I find out.
Play a mean game, Diary,
