If you like bad movies you'll love www.badmovies.org. I love the "things I learned from this movies" section.

Here is the list from the killer clowns from outer space review.

Things I learned from this movie:
-Every girl wants to make out in an rubber raft in the back of a 4X4.
-Spaceships use darkroom doors.
-Balloon animals are terrific bloodhounds.
-Special effects need not be special.
-Shadows can eat people.
-Always shoot a clown, I mean Klown, in the nose.
-Main characters do not get killed, ever, even though everybody else does.
-The older cop is always the asshole.
-State police consist of about eight patrol cars.
