JUST when you think the tides washing in semi-celebs and has- beens with reality shows have ceased, another wave hits like a tsunami.

So, it was with great and terrible dread, that I sat down to watch Luther (Luke) Campbell’s new VH1 reality show called “Luke’s Parental Advisory.”

Luke who?

Luke Campbell of 2 Live Crew, that’s who. Now, if your memory is still intact, you may remember that he’s the guy who put the booty into the big biz of hip hop, and he’s also the guy who took his freedom of speech issues (2 Live Crew’s “As Nasty as They Wanna Be” was banned in Florida) all the way to the Supreme Court – and won.

Be that as it may, if there’s anything we’ve learned from watching these rock and hip hop stars on their reality shows – including “Gene Simmons Family Jewels” – it’s that their home lives are grindingly boring.

But “Luke’s Parental Advisory” is surprisingly fresh and funny. The guy is very smart and knows that he’s the entertainer in the family, and so hedoesn’t place too much heat on the several kids who live with him to be clever.

Anyway, Luke is about to marry his girlfriend, a 27-year old attorney, Kristin, who not only runs the legal end of his businesses, but seems to fit very well with Luke and his brood.

When they go to pick out a wedding cake, she explains to him that they will freeze the top of the cake to eat it the following year on their anniversary. He looks at her like she’s nuts.

“Your daddy’s a doctor, mine was a custodian. We didn’t freeze no wedding cake – there wasn’t room in the refrigerator!” he declares.

When Luke starts giving his teen daughter the third degree on boys, he explains to her that, “Boys who date more than one girl – they’re cool. A girl who dates more than one boy is called a slut!”

Disgustingly sexist sure, and probably the truest thing you’ll hear on TV this summer.

On the way to the barber shop he says he’s gotta get his hair cut every week to keep it from looking crazy because, “I don’t want to end up on MySpace looking like a crack monster!”

When Kristin finds a porno video under Luke Jr.’s mattress, she calls Daddy, who happens to be at a strip club auditioning strippers for his music tour. Luke comes home and tells the boy that those videos are not acceptable and he’s too young to watch that junk.

The boy, naturally says, “You’re the one making all those (adult) videos – and you started in high school.” A normal guy would back down in the face of such hard evidence, but Luke Sr. he keeps going.

“Am I clear?” he says at the end of the lecture. His son answers, “Clear.” Then Sr. affectionately says, “Crystal clear?” “Crystal clear,” Jr. answers, and somehow you know you’ve just seen one of the most honest moment on TV this summer. Charming.
