Nothing by way of crude, tasteless, sex-obsessed teen comedies should surprise us these days. What's surprising about "Superbad!" is that it's really funny -- in a charmingly deplorable way.

We'd expect no more or less from the film family of producer Judd Apatow, creator of "The 40-Year-Old Virgin" and "Knocked Up." Our entry at hand co-stars (and was co-written by) his "Knocked Up" hero, Seth Rogen.

The time-tested phallocentric plot here concerns two best-buds-forever geeks at the end of their senior year, desperate to lose their virginity before heading off to college. Their respective dreamgirls, who hitherto haven't given them the time of day, invite them to THE hot graduation party on the boys' promise to bring the booze. Plan of action: Get the girls wasted, and sex is guaranteed.

Well, they do not plan "to have sexual relations" with these women. It's the scaled-down Monica Lewinsky kinda action they want. But it's a shaggy cock-and-bull story they (and we) get.

The calm, cute boy is Evan (Michael Cera), who'll soon be going to Dartmouth. The un-cute and uncouth boy is Seth (Jonah Hill), a fast-talkin' fatso with a hormonal excess of frightening proportions: "It's not fair girls get to flaunt their [breasts], but we've gotta hide every [erection] we get."

Seth spent his whole childhood drawing penises. Now, on top of terminal horniness, he is also suffering from major separation anxiety vis-a-vis Evan: Dartmouth rejected Seth but accepted their nerdy classmate Fogell (Christopher Mintz-Plasse).

Seth would happily murder Fogell, but for the fact that Fogell has a fake ID (under the name "McLovin") and is thus the only one who can get booze. But just as a bored liquor-store clerk lets him make the purchase, a robber bursts in, empties the cash register and knocks Fogell out.

Officers Slater (Bill Hader) and Williams (Seth Rogen) arrive on scene, two truly demented cops, who offer Fogell a ride home, stopping first at a bar for some heavy under-and-overage drinking.

Wisdom dispensed by Officer Slater includes: "Don't marry a chick you meet in a bar. Go to a farmer's market or a pumpkin patch, depending on the time of year. ... I met my wife at paintball."

Fogell is continually sidetracked from his mission by the insane shenanigans of the cops, who drag him along on their calls, while the girls wait impatiently for their booze. But the party scenes, once we get there, are worth the wait. In the off-the-wall best, some mean cokeheads mistake Evan for somebody else's brother and force him to sing the worst-ever rendition of the worst-ever song, "These Eyes."

Cera comes to us from the brilliant TV series "Arrested Development," where he played the perpetually nervous grandson of a man jailed for shifty accounting practices. Here, his ingratiating, straight-faced tenor delivery is just as funny, and he blends well with the generally obnoxious Hill. Their dreamgirls (Martha MacIsaac and Emma Stone) are effectively realistic, as opposed to the bimbo-stereotypes usually found in such fare. And the two cops are hilarious.

But the show is totally stolen by Christopher Mintz-Plasse -- a name not made in heaven for movie marquees. As "McLovin," he reinvents the dweeb, above and beyond Jon Heder's Napoleon Dynamite or anybody else's adolescent misfit. I predict cult stardom for this kid, if not an Oscar nomination for supporting actor!

"Superbad" is a sort of "American Pie/Graffiti" combo sandwich -- a frat-house keg flick, but with smarter timing and acting and more honest humanity in its characters than is usual for the genre. Give credit for that to director Greg Mottola (a Carnegie Mellon and Pittsburgh Filmmakers alumnus whose excellent debut film was "The Daytrippers" a decade ago).

As it is, you couldn't ask for a more anarchic, outrageously profane, sophomoric heir to the freshmanic "Animal House" concept. How gleefully raunchy is this? To find out, stick around through the final credits, which are festooned with the most grotesquely "creative" collection of penis drawings ever assembled.

Well, let's face it -- it's a funny appendage. And in the cornucopia of phallic gags here, "Superbad" is truly an organ donor.
