Crystal Harris, Claire Sinclair and Jessica Burciaga were just a few of the slew of playmates that descended on Vegas this weekend to celebrate the joint birthday parties of Hugh and Marston Hefner. Luckily for you, where there are playmates, there are also twitpics. Enjoy.

Boobs and Cake. So maybe they aren’t as natural a pair as milk and cookies or football and beer, but let’s face it, breasts go great with everything. And if there’s one man that can testify to this truth with a greater knowledge and appreciation than any other, it’s Hugh Hefner. We know Hef has seen a obscene amount of boobs in his day, and probably a few boob cakes too. So it makes perfect sense on Hef’s big day that we offer him many breast wishes with this gallery of boob-shaped baked goods

Talk about staying power. At 85, the world’s most legendary bachelor is about to tie the knot for the third time to December 2009 Playmate of the Month, Crystal Harris. In honor of Hef’s Bday and his commitment to Crystal (and his obvious commitment to Viagra), we’ve rounded up the hottest pictures of all his known girlfriends. And while we’re sure Hugh’s had many more girlfriends in his 85 years, we’re absolutely convinced that these 17 are the sexiest.

There’s no place better to throw a party than at the Playboy mansion. Of course, having hundreds of beautiful women who are willing to strip down to nearly nothing certainly helps. But it’s the girls wearing only the mark of an painter’s brush that make Playboy’s Mansion Parties legendary. Perhaps no one knows this better than the birthday boy himself. In honor of Hef’s 85th and Marston’s 21st birthdays, we give you 112 of photos of the mansion’s most cunning walking canvases. Enjoy!

For many college students, grads, and young professionals, a career path can be a cloudy one – a mixture of doubt and confusion, purpose and experimentation. For Mr. Hefner, it was a journey many others could sympathize with but no one has duplicated. He served as a writer for a military newspaper in the U.S. Army. He graduated from the University of Illinois at Urbana-Champaign, worked as a copywriter for Esquire then raised $8,000 from 45 investors to launch Playboy. The rest is history. We’ve collected almost 40 photos of Hef during these formative years. Prepare to stare into the face of determination after the jump!

For the first time in COED’s history, we’re dedicating an entire weekend of content to one person. Who could be worthy of such an honorable distinction? Well, he’s the reason we, and every other red-blooded American media-savvy male got into publishing in the first place. He took men’s entertainment to an entirely new level by stimulating the mind and eye with a combination of provocative pictorials, witty illustrations, gripping fiction from renowned authors, controversial interviews, and heavy fodder for debate. He’s Hef and Saturday, April 9th is his birthday. This is our gift to him. Read more after the bunny hop!

JWoww and Mel Gibson’s ex might’ve turned down offers to pose for the gentleman’s mag, and Hef might move corporate headquarters out of Chicago, but there is one sure thing about Playboy. They throw SICK parties. Halloween is the perfect opportunity to see chicks wearing skimpy, skin-baring costumes. So, you can only imagine what a Hal… Click to read more
