Behold! The horrors of too much plastic surgery!

In “V/H/S,” opening Friday, bad guys film themselves finding movies of other bad guys. At least they get to see those movies in their entirety, which we never got to do with these films-within-films.

“Angels With Filthy Souls”
A parody of a noir-gangster flick, this is the film that Kevin in “Home Alone” uses to get out of answering the door for the pizza man. It also brought the phrase “Keep the change, you filthy animal” to playgrounds everywhere.

“Simple Jack”
You want an Oscar? Play someone with a disability. That’s why Ben Stiller’s character in “Tropic Thunder” starred in this movie about a character who’s essentially Forrest Gump’s slower (in every sense) younger brother.

“The Dueling Cavalier”
The film that might destroy silent film star Lina Lamont’s (Jean Hagen) career in “Singin’ in the Rain” involves — gasp — sound and singing. Since she sounds like Bobcat Goldthwait gargling gravel, a plan is hatched, people fall in love, and Gene Kelly frolics in a storm.

“Chubby Rain”
In “Bowfinger,” a producer (played by Steve Martin) shoots a sci-fi action movie featuring a big star (Eddie Murphy) who doesn’t even know he’s on film. All of a sudden “Plan 9 From Outer Space” looks good.

“Asses of Fire”
The Canadian “Terrance and Phillip” movie within “South Park: Bigger, Longer & Uncut” goes beyond absurd, eventually inspiring the U.S. to invade Canada. That’ll teach ’em.
