On a recent episode of his popular podcast, former Fear Factor and Man Show host and current UFC commentator Joe Rogan defended same-sex marriage against opponents he felt were acting like "weak-ass bitches."

Because there are too many shows about teachers and scientists and artists and hobos out there, one network is boldly doing a show about lawyers. Also today: a doctor becomes a ghost dad and Joe Rogan is back, ladies.

Joe Rogan is famous for many things. He hosted "Fear Factor," he commentates for the UFC, and he's also a very funny and often times overly vulgar stand up comic, when he's not ripping off other people's material.

I don't know what's grosser here: The gleeful pervert grinning at ultimate fighter and former Fear Factor host Joe Rogan, or that Joe uses a soundtrack of pig snorts, whips, and the phrase "Ride 'em cowboy" for this video.

We dispatched Defamer videographer Molly McAleer to the 2007 High Times Stony Awards (congratulations to Stoner of the Year Seth Rogen!), where she enticed munchies-afflicted celebrities strolling down the green carpet with homemade snickerdoodles and an inviting smile. It was a potent combination, that got Tommy Chong to open up about the "unauthorized" Cheech n' Chong biography he's writing, and Lindsay Lohan's main Mean Girls homegay, Daniel Franzese, to employ an arm-breaking metaphor in discussing her recent cokepanted troubles.

Carlos Mencia verbal bitchslapper and crusader on behalf of plundered stand-ups everywhere Joe Rogan checked in with the folks over at Cracked.com, covering a variety of topics, including his thoughts on fame himself—something he now enjoys in large quantities thanks to six seasons as host of the groundbreaking televised goat-testicle-eating contest, Fear Factor:

Back on Wednesday, we passed along a video (still available here) of comedian and Fear Factor master-of-bovine-anus-devouring-ceremonies Joe Rogan confronting Carlos "Mind Of" Mencia about the widely held belief that Mencia helps himself to other comics' material (which, to his credit, he at least has to courtesy to transform into something completely unfunny). Since the release of comedy repo man Rogan's whistleblowing exposé, it seems the fight has been pretty lopsided in Mencia's favor, as Rogan blogs that he's been given a time out at the Comedy Store (the site of the confrontation) and lost an agent over the brawl:

Because Valentine's Day (yes, it's today—remind your married boss to send you out to obtain enough champagne to fill his Jacuzzi, which should probably buy him another year of boning the second assistant before divorce papers are filed) is a celebration of love, we pass along this video of a Saturday night Comedy Store quarrel between accused joke appropriator Carlos "Mind Of" Mencia and comedy repo man Joe "I'm A Famous Multi-Millionaire" Rogan, who finally have it out over Mencia's utter inability to get a laugh with other comics' material. Yes, their bickering gets quite heated and loud at times (and goes on at length—make liberal use of the fast-forward function of the YouTube slider bar), but one can't ask that such passion be expressed quietly. Happy Valentine's!

The Best Week Ever Blog reprints an exchange between Fear Factor host (or, according to some reports, ex-host) Joe Rogan and a MySpace "hater," whom when he e-mailed Rogan to offer constructive criticism about his comedic ability ("Joe Rogan, I hate you... you're not funny... "), probably didn't expect the prolonged flame-war that ensued. The back-and-forth gets a little repetitive, with Rogan perhaps falling back on the rhetorical A-bomb about the size of his bank account too much (though if we've learned anything from living in Hollywood, it's that one's personal worth is directly proportional to one's net worth), but here's a sample from the middle that will give you the gist:
