Donny, though, discovers he owes the IRS more than $40,000. Even worse, he sees Todd's engagement photo in a publication and discovers that his son has changed his name and made up a story about his parents dying in an explosion. He's offered a large sum of money by tabloid TV host Randall Morgan (DAN PATRICK) to do a reunion show from prison featuring Todd and Miss McGarricle (later played by SUSAN SARANDON).

Donny tries to reconcile with Todd and get to know his fiancée, her military brother Chad (MILO VENTIMIGLIA), and their parents (BLAKE CLARK and MEAGEN FAY). He also reconciles with his best friend and fellow disgraced celebrity Vanilla Ice (HIMSELF). But his efforts to reach out to his son are complicated by his growing suspicions that Jamie is up to no good.

But I can't deny that this time out I didn't laugh out loud on numerous occasions. I guess Sandler's kids must be grown up now or at least at an age where he has decided to stop making schmaltzy, PG-13 yuk and yuck fests. He's gone for a hard R here. And there are gags and extended bits that are every bit as raunchy and naughty to guffaw at as the hijinks those ladies in "Bridesmaids" engaged in last year. If written smarter and starring a different leading man - say, a Vince Vaughn or a Will Ferrell - this could have been the male answer to Kristen Wiig's hit comedy considering it also revolves around a wedding that features a groom and best man with issues.

But Sandler keeps getting in the film's way with his snickering, wink-wink performance and frequent digressions into truly sick and perverted territory. On one hand, you can commend the film for its go-for-broke attempt at goosing its audience. On the other... man, there's some sick and twisted stuff in this flick!

Sandler stars as Donny Burger, a 40-something loser who gained famed back in the 1980s for impregnating his hot junior high school teacher (Eva Amurri Martino). When hot for teacher was sentenced to prison, Donny was forced to raise the baby as a single parent. Needless to say, he screwed up royally, naming the kid "Han Solo," stuffing him with sweets, and using him as a designated driver. Now, grown up, that kid (Andy Samberg) has changed his name to Todd, broken off all contact with Donny, and found success as a hedge fund manager and the fiancée of society sweetheart Jamie (Leighton Meester).

When Donny is offered $50,000 by a tabloid TV host (Dan Patrick) to reunite with mother and son in prison - a sum of money that would get him out of debt to the IRS - he tries to reconcile with Todd. The rest of the film has Donny's wild ways bringing Todd out of his conservative shell all the while we know the relationship is headed for disaster again once Todd finds out about Donny's secret deal.

What really distinguishes "That's My Boy" is not the two leads, but all of the great, GREAT cameo appearances that are sprinkled throughout this film. For once in a Sandler movie, the oddball, stunt casting works. No one is in it just for a scene or two of "Hey, look it's Johnny Depp!" James Caan has great fun as a hyper-violent Catholic priest always ready to throw a haymaker. Vanilla Ice is actually really funny as a parody version of himself, now working at a hot dog stand run by Todd Bridges of "Diff'rent Strokes." Other surprises abound from such disparate celebs as Susan Sarandon, Tony Orlando, and New York Jets head coach Rex Ryan. And fans of "Saturday Night Live" will delight as a veritable cavalcade of past cast members show up to make their mark, ranging from Will Forte to Ana Gasteyer to Rachel Dratch.

If your threshold for smut is high and you stick with this flick, I think it has its rewards. I can't give it a blanket recommend because...well, you just don't want to take a blue light to that blanket and see what's on it after two hours of Sandler smut. But it's a comedy. I laughed. It's a simple as that. I rate it a 5.5 out of 10. (T. Durgin)
