Before Kaley Cuoco and Lindsay Lohan, other famous faces (and their parts) have appeared in Playboy. Here are some of the sexiest celebrities to follow in Marilyn's footsteps.

Takes on goat.

Seriously, that thing's as big as my dog.

Looks like something that would happen at the Playboy Mansion.

Makes me wanna sleep.

Watch and learn how to do the macarena from these sexy ladies.

Yesterday PETA unveiled the latest ad for its "I'd Rather Go Naked Than Wear Fur" campaign, featuring Bethenny Frankel, member of People with Extraordinarily Little Talent Society (PELTS).

My Cheetah-lined hat is off to you, PETA, because your ads continue to intrigue me. I find myself thinking, as I cut into my still-mooing T-Bone, "Who is PETA's demographic?" Considering your recent choice of spokespeople, I can only assume that your research, presumably conducted by underpaid monkeys at typewriters, shows that your core audience is people invested in reality television. How else can you justify burning our retinas with the likes of Steve-O, Khloe Kardashian, and Karina Smirnoff? (You know it's bad when your last name is a brand and they still don't want you.)

It makes sense though. PETA's invasive studies done on bunnies, show that reality TV viewers are far less intelligent people who can be more easily swayed into giving up those necessary extravagances like fitted Dalmatian tees adorned with hamster noses, and squirrel-tail tampons.

And as for the rest of us, the nod-and-wink, upper-crust "Adult Swim" viewer? Manatee flippers make for a lovely corset.

Hugh Hefner. The dude has obviously gone off the rails. During the last season of Girls Next Door we could kind of see that he was losing it, but this just confirms everything. Sure, she looks decent on this cover, but what will you find once you open up those pages? Our guess is after the jump.

In this month's Playboy Magazine, supernerd James Cameron said he designed his female Avatar aliens with breasts, even though they're not placental mammals (don't worry, we have no idea what that means either!). Since the movie cost around $500 million and it's in 3D, we can only hope that those boobs are so amazing they pop out of the screen and punch us in the face so hard they give us a black eye. We hope! But what if they aren't? Whose computer generated/animated boobs will you fall back on?

We've always been partial to Angelina Jolie in Beowulf, which you probably didn't see because the movie sucked. But damn, look! They even made her eyes look like she wants nothing to do with us, just like in real life!
