After just 20 minutes on the phone with Paris Hilton and Nicole Richie, you can actually feel your brains cells vanishing.

The two celebutantes were promoting their new season of The Simple Life:Interns, that has them packing up their Louis Vuitton briefcases and venturing out into the corporate world.

Getting them to actually talk about the show and their benevolent elbow-rubbing with "regular" people was about as painless as a bikini wax.

"We consider ourselves to be regular people," says Richie.

Oh, no. Not even close.

But to their credit, the journey that took them across America to intern at jobs which intelligent and more deserving people would kill for, taught them many lessons.

"I learned how to change oil in a car and fix a broken tire. It was pretty hot," says Hilton.

"I learned a lot from the day care, because I want to be a mom and have five kids," says Richie.

God help us.

The girls also learned there are five things you can't leave home without.

"Our iPods, MAC makeup, digital camera, Dior sunglasses and each other," says Richie.

But, the learning didn't stop there.

Richie discovered she has psychic powers.

"But instead of reading palms, I read people's butts," she says. "And someone farted."

Hilton also realized if she wasn't a billion- dollar heiress, famous for the sake of being famous, and had to get a real job to, say, survive, she wouldn't work at a funeral home.

"It sucked," she says of her stint at a funeral home this season. "We just didn't like it because we don't like dealing with dead people. It's gross."

Both girls say after interning with a plastic surgeon, they'll never be cosmetically altered.

"I found it really gross, the cutting of the skin," says Hilton.

Her brain's other half agrees.

"I would never get a boob job because I like being flat," says Richie.

Yeah, right. We'll see if that's still the case when gravity gets a hold of them.

Richie also discovered a certain love of wild animals, during a zoo episode.

"The giraffes and elephants were hot," she says. "I wanted to French kiss them."

And since The Simple Life: Interns is a show about learning, there are lessons the audience will no doubt take away as well.

First, yes Hilton and Richie are that dumb.

Case in point, in one episode Richie doesn't know that New Jersey is a state.

Also, Hilton's annoying catchphrase "that's hot" isn't likely to die anytime soon.

And being a billionaire allegedly grants you immunity from political correctness. Take their Greyhound bus adventure for example.

"There was this boy with Tourette's syndrome and a lot of people would want to sing for us and he would have Tourette's on beat," says Hilton laughing.

She may get away with more, but being filthy stinking rich won't get her into Brad Pitt's newly single arms any easier.

"No, cause I love Jennifer Aniston. They're both hot," says Hilton.

And finally, viewers be warned, things are about to take a sharp turn for the worst in the music industry. The girls will each be releasing an album this year.

Richie's album will be very instrumental and Hilton's will be a medley of pop rock and hip hop.

"It's hot," she says.
