With Scary Movie and White Chicks, the Wayans brothers -- Keenan Ivory, Shawn and Marlon -- came shockingly close to surpassing Rob Schneider as the reigning champions of moron comedy.

Now they have accomplished the seemingly impossible, as the Wayans' Little Man inches the brothers ahead in that dubious competition. Hell, Schneider himself even makes a cameo in the flick, perhaps a sign that even he realizes he has been bested at being worse.

The nominal plot involves Calvin (Marlon Wayans), a tough but pint-sized thief who teams up with his idiotic partner (Tracy Morgan) to swipe a huge diamond for a mobster (Chazz Palminteri). After barely eluding police, Calvin is forced to ditch the jewel in the purse of an unsuspecting bystander. As it turns out, the purse belongs to a career-minded woman named Vanessa (Kerry Washington), whose husband, Darryl (Shawn Wayans), is desperate for the couple to have a baby.

The plot thickens. Calvin, needing to get into the couple's home and retrieve that diamond, puts his diminutive stature to use. He poses as a baby left on their doorstep. Vanessa and Darryl are not fazed that the toddler has the mug of a grown man, much less that he sports a tattoo on his forearm. A doctor who examines the would-be child is equally oblivious. Needless to say, Little Man is the sort of movie in which stupid characters continually do stupid things, if only to set the stage for more stupid happenings.

Not a single character here appears cognizant that little adults actually exist. Nothing shakes the young couple's assurance that Calvin is anything but a baby -- even after he steals Darryl's car and is chased by police.

But, hey, why should any characters be suspicious? The filmmakers themselves must not be familiar with dwarves, either. After all, they evidently believed Calvin had to be a CGI creation, as Marlon Wayans' head is digitally grafted on to a little person's body (with young Linden Porco providing the aforementioned physique).

The special effect is presumably because no actual actor of small stature was suitable for the complexities of a role that calls for rubbing a chocolate chip cookie all over his crotch, swallowing dog urine and enduring the humiliation of an anal thermometer. From soiled diapers to busty hotties offering to breastfeed, no joke is too obvious or odious for this clunker.

Some talented people turn up here -- Palminteri, Alex Borstein, In Living Color alums David Alan Grier and Kelly Coffield -- and all, without exception, are wasted. Molly Shannon appears for a particularly unfunny cameo. What gives? Do all these folks have huge gambling debts or something?

Mastered in high-definition, this 1.85:1 anamorphic widescreen print transfer is of excellent quality. The picture is consistently clean, sharp and free of any noticeable defects (unless you count the movie itself, that is).

The Dolby Digital 5.1 is solid, if unremarkable. Audio and subtitles are available in English and French.

The DVD lives up to its billing as the "Loaded with Extra Crap Edition." As you would expect, a commentary featuring the three Wayans brothers is buoyed by an easygoing banter; even their self-satisfaction with the flick has its endearing side. Still, it's not exactly enlightening information. Maybe that's the point. As Marlon Wayans cracks here, no one but "desperate filmmakers" even listens to DVD commentary.

The 15-minute, eight-second Big Comedy: The Making of Little Man is a concise featurette in which cast and crew discuss how the movie came together. It's instructive to hear Shawn Wayans explain that Little Man is best enjoyed if you "take your brain out of your head and have a ball." He fails to mention that the next step involves the filmmakers feeding the aforementioned brain to a parakeet.

Generous portions of 11 deleted scenes and five extended scenes are included, making for a combined running time of 28 minutes and four seconds. Aside from some extra jokes involving bodily function and getting smacked in the crotch, the bonus material is mainly of interest to see some pre-CG footage of young Linden Porco filling in for Calvin.

From the Ground Up: The Visual Effects of Little Man is a compelling window into the painstaking work that resulted in grafting Marlon's head on to 9-year-old Linden Porco. If nothing else, the meticulousness of the special effects crew is impressive.

Perhaps the most entertaining featurette is Linden's World (11:17), which profiles the Canadian boy who provides the body for the title character. Linden is an engaging and enthusiastic kid; it's regrettable that such a good kid is connected to this pabulum.

Method or Madness is a throwaway featurette (3:34) that hardly merits explanation. Kids might enjoy it. The DVD also includes previews for The Pursuit of Happyness, Casino Royale, Ghost Rider, Stomp the Yard, Click, The Pink Panther (2006), White Chicks, The Benchwarmers, The Da Vinci Code, Talladega Nights: The Ballad of Ricky Bobby, Gridiron Gang, Crossover, Monty Python & the Holy Grail and Coming to Blu-Ray.

If you're bound and determined to see a grown man dressed like a baby, here's some advice: Search the Internet instead. It's certainly cheaper. And probably funnier, too.
