The title of the latest lowbrow yukfest to try and sneak into theaters without being noticed by critics appears, on posters, as “InAPPropriate Comedy,” a reference to the fact that its grab bag of short sketches pop up as if they were being haphazardly generated by a tablet computer app.

That much, at least, is truth in advertising. The 20 or so skits — featuring headliners Rob Schneider, Adrien Brody, Michelle Rodriguez and Lindsay Lohan, along with a supporting cast of nobodies — are like that freebie quote-a-day-app you downloaded and then almost immediately regretted: random and repetitive. A more accurate title would be “Inept, Inadequate and Insipid Comedy.”

The movie is the brainchild of former ShamWow pitchman Vince Offer, who’s credited with directing, co-writing, producing and acting in this seemingly improvised, yet bizarrely stale assortment of crudely misogynistic, scatological, phallic and racist jokes. The opening skit pokes fun at the movie “127 Hours,” which came out more than two years ago.

The rest of the humor is equally dated. “Inappropriate Comedy” also targets such long-defunct TV shows as “Jackass” — with an offensive series of six parody skits called “Blackass” — and the 1971 movie “Dirty Harry” — with three separate sketches starring Brody as an effeminate, double-entendre-spewing “Flirty Harry.”

The lack of topicality can’t be blamed on production delays. “Inappropriate Comedy” has no special effects, elaborate sets or costumes. It feels like it could have been thrown together over a couple of weekends, fueled by a keg or two of Budweiser.

The target demographic, presumably, is the same one that laughed at “Jack and Jill” (which also, unsurprisingly, featured cameos by Offer and Schneider).

Ari Shaffir, who co-wrote the film with Offer and Ken Pringle, brings a spark of life to his performance in “The Amazing Racist.” Playing a bluntly clueless bigot who confronts Asians, blacks, Jews and Mexicans, the stand-up comic appears, again and again, in a series of skits meant to evoke the hidden-camera hilarity of “Borat.” The joke quickly wears thin.

More original, if even less funny, is a “Blackass” skit in which several men watch as one of them tempts a mouse toward a mousetrap with a dab of spray cheese that has been applied to his penis.

The result is, predictably, painful.
