Vanilla Ice is back, back baby.

And for that crime alone, Adam Sandler should get the chair.

Alas, it's a minor offense in "That's My Boy," a no-holds-barred raunch-fest that combines bits of "Saturday Night Live" skits and "The Hangover" with every ugly Sandler laugher ever made.

When your comedy starts with a criminally "inappropriate" sexual relationship between a 13-year-old boy and his bombshell teacher, the scariest thought is "Yeah, they're going to have to top that." Which they then proceed to do.

Sandler has made worse movies, but never one as grotesque as this.

He stars as Donny Berger, who became famous — notorious — in the '80s for his illegal fling with Miss McGarricle (Eva Amurri Martino). Donny made a lot of money being the kid who lived Van Halen's "Hot for Teacher" fantasy. Of course, he blew through all that cash. Thirty years later, all he has to show for the glory days are a dated TV movie about the affair, his old Fiero and a whopping tax bill.

Donny's one hope — find his estranged son, whom he named "Han Solo Berger," and stage a reunion with the kid and the imprisoned mom on a sleazy TV show.

You will not believe how unfunny "Saturday Night Live's" Andy Samberg can be until you see him as this guy. There are a staggering number of shock-for-shock's-sake scenes that go on, ad nauseam. And through it all, Sandler aims low and sometimes hits his targets. Maybe the best joke is how "good looking" and "sexy" all the women say he is, how charmed every character seems by his oafishness.
