Surfing the websites of ''SNL'' top grads -- Dana Carvey, Chris Rock, and Adam Sandler have online homes that are worth visiting

When considering the ”Saturday Night Live” alumni starring in this summer’s films, a quick search reveals one of the more interesting ironies: The biggest stars among the group — Mike Myers (”Austin Powers in Goldmember”) and Eddie Murphy (”The Adventures of Pluto Nash”) — have shockingly pitiable presences online. (”Mike Myers Nude,” anyone? Didn’t think so.) No, it’s Chris Rock (”Bad Company”), Adam Sandler (”Mr. Deeds”), and Dana Carvey (”The Master of Disguise”) who have sites that are worth more than a couple of clicks. We take a closer look.

Carvey, of course, is the master of wickedly funny impersonations, which probably explains the thinking behind his upcoming high-concept costume-athon, ”The Master of Disguise” (exec-produced by Sandler). So why doesn’t this perfectly agreeable fansite have more audio clips of his best impressions? There’s only one each of his Ross Perot and George (”Wouldn’t be prudent”) Bush — and Carvey’s spot-on Johnny Carson is nowhere to be heard. Better represented are Carvey’s most famous creations, the Church Lady and Garth Algar, as well as relatively timely updates about the comic himself, but ultimately this website really isn’t that special.

With Rock’s star rising by the minute (despite ”Company”’s disappointing box office), some may be miffed that there’s not more substantive news about the no-holds-barred comic on this otherwise impeccably well-maintained site. No matter. Fans will drool over the bounty of both audio and video clips of his most incendiary (and hysterical) routines, culled from various stand-up specials and skits off his HBO series, ”The Chris Rock Show.” The collection does include some of Rock’s most infamous material, so be warned: Many of the clips are so long and so profane that they could easily strain both your PC and your politically correct sensibilities.

The only ”official” site of the bunch, and we do mean official. Sandler oversees the site’s content personally, using tracks from his 1999 comedy album, ”Stan and Judy’s Kid,” for several well-executed Flash sketches, as well as supplying regularly posted messages from Adam. Updates from the set of ”Anger Management,” scheduled for release next summer, are especially full of the sort of goofball irreverence one expects from Sandler — which is doubtless why costar Jack Nicholson is nowhere to be seen. (Oddly, or perhaps understandably, there’s barely any mention of Cannes darling ”Punch-Drunk Love,” in which Sandler demonstrates he is capable of — gasp! — real, nuanced acting.) The site’s real showstopper, though, is Sandler’s beguiling bulldog Meatball. With more than 25 vignettes already online, this adorably deadpan dog could very well become the biggest online animal star since the spokespuppet. A
