My choice is Bad Ben by Nigel Bach. What a treat. There are like 8 of them and each of them is a real gem. What I love about it is that these films are made just by an older guy with a massive house who thought "how about I make some found-footage films since I have all this space", originally it was semi-serious but then he just accepted that it's so silly and started to go along with it, making more fun of both himself and the films themselves.
