intro: Celebrities aren't above enduring a little embarrassment for a good cause or the right price, especially if their pockets are a little "lean."
Still, "Baywatch" fans may be shocked by David Hasselhoff's new turn as Gunther "Mr. Lean" Hasselhoff, a German-accented man he plays in an ad touting the "hot delicious goodness" of Lean Pocket microwaveable sandwiches.
Wearing a face full of makeup and looking like Liberace's younger brother, Mr. Lean introduces himself as a lifestyle consultant. In the ad titled "Lean Pockets: A Fashion Intervention," Mr. Lean offers fashion advice for the office (hint -- wear more green) and seems to being giving fitness tips as he dances a jig with a young girl while chanting "do it, do it, do it."
Of course, everyone is encouraged to eat Lean Pockets. Inexplicably, the ad also features lots of cats, one in a litter box. It might seem a far fall from Hasselhoff's former gig on "Britain's Got Talent," but as Mr. Lean says in the ad, "life is all about making the right choices."
Click through to see seven other celebrities who have put their dignity aside to endorse products and tackle topics most people would be too embarrassed to talk about in public.
quicklist: 1 category: title: Lissa Rinna for "Depends" url: text: In a commercial for Depend brand adult diapers, "Days of Our Lives" actress Lisa Rinna shows off her famous pout and posterior while posing on the red carpet in a form-fitting dress -- with Depend's new Silhouette for Women underneath.
"I am wearing an evening gown for God's sake! And you can't tell I have it on. Check out the booty!" Rinna gushes, turning around. "It feels great -- and they're so soft."
Even her husband, Harry Hamlin, put the product to the "touch test," running a finger down her backside. "You can't even tell she's wearing it," he declares.
Rinna, 48, insists she has nothing to be ashamed of.
"I am a champion for positive self-image for women," she says in the ad. "The new Silhouette makes a woman feel confident, and it's fashionable.
Moreover, Rinna is endorsing the brand for a good cause: Depend maker Kimberly-Clark agreed to donate $225,000 to Dress for Success, a charity she supports.
"I don't endorse many products," Rinna, who does not personally wear adult diapers, told the Huffington Post. "When I was first asked, I was surprised. I'm not the first person you think of when you think of Depends. That's what I love about it. I believe women should feel good about themselves and if that means they need to talk about their problems, then absolutely. We need to help each other. I was not afraid to do this." media: 16125972

"Being Armenian and hairy, I thought [TRIA] was the perfect product," she said in the documents. media: 16125949
