For all we know, the Katherine Heigl / Josh Duhamel romantic comedy "Life As We Know It" (which opens today) is truly great.

But it sure feels like a generic flick whose basic components were pulled out of a hat: popular actress, safely adorable actor, cheesy and weak title, initial hatred, tragic circumstance, and eventual love. Even the preview -- which willfully gives up the entire plot in 30 seconds, as if the studio knows there's no point in playing coy -- is set to the overused "Solsbury Hill" by Peter Gabriel. (For real, as soon as you hear those guitar chords, you're like, "Wow, I've been here before. A hundred times.")

It was enough to make us wonder if one actually could pull bits and pieces out of a hat to create a film just as plausibly real as this one. So, we wrote a basic movie-premise Mad Lib, then plugged the holes with answers supplied by our trusty baseball cap: five names of rom-com regular actresses, five male leads of varying fame levels, five plot concepts, five co-stars, and 10 title words randomly paired.

The resulting fake flicks are listed below -- the bits we plugged in are underlined -- along with our rating of whether these Mad Lib movies seem far-fetched or the real deal, using a scale of 1–5, with 1 being No Way and 5 being Order HBO Now And Make Popcorn In Your Pajamas.

1) In "Foolish Hearts," an uptight professional with no social skills (Kristen Bell) and her shrink (Ashton Kutcher) fall in love after pretending to be married for contrived reasons. Co-starring Selma Blair as Bell's BFF, a sassy "fat" girl.

Trailer song: "Let My Love Open the Door," by Pete Townsend

Plausibility: 3. Bell has kind of already played this character in "When in Rome," and you just know someone will convince Selma Blair that fat suit = Golden Globe. However, this lost a point because not even Aston Kutcher thinks he can believably play a psychologist.

2) In "Burning Romance," a chef (Jennifer Garner) and her competitor (Gerard Butler) fall in love after witnessing a bank robbery. Co-starring Christina Applegate as Garner's BFF, a frumpy cat lady.

Plausibility: 4. Garner and Butler both have terrible taste in comedies, and hey, people love bank robberies. It's like the rom-com version of "The Town," directed by Garner's hubby Ben Affleck. Maybe he could play the heart-of-gold bandit who brings them together.

3) In "Passion Train," an undertaker (Cameron Diaz) and her oncologist (James Marsden) fall in love after daring each other to go on 20 blind dates. Co-starring Rupert Everett as Cammy's BFF, a fabulous gay man.

Trailer song: "Every Little Thing She Does Is Magic"

Plausibility: 1. What kind of a cancer doctor is daring his patient to do anything other than stay alive? And wouldn't he be the one doing the magic? And you just know the studio would worry that the titular train refers to a family-unfriendly sex act.

4) In "Hating Benjamin," an up-and-coming interior designer (Drew Barrymore) and her boss (Matthew McConaughey) fall in love after getting snowed in somewhere quaint but wacky. Co-starring Mark Ruffalo as Drew's BFF, the hot guy she'll decide she loves late in the movie, who will then conveniently ignore that she's basically settling for him because the other guy was a douche.

Trailer song: "This Will Be (an Everlasting Love)" by Natalie Cole

Plausibility: 4, but only because we're not sure Ruffalo needs to pay the mortgage this bad.

5) In "Central Love," a reporter (Jennifer Aniston) and her irritating man-whore neighbor (Josh Lucas) fall in love after running for office against one another. Co-starring Judy Greer as Jen's BFF, a drunken nympho.

Trailer song: "Suddenly I See," by KT Tunstall

Plausibility: 5. We can smell the money burning right now.
