Here we go! Time for the fighters to step on the scale and show us if they're ready for Saturday night. One last time we get the UFC 100 commercial promoting the top three fights on the card - Lesnar v. Mir, GSP v. Alves and Hendo v. Bisping. Mike Goldberg welcomes us to the Mandalay Bay Events Center, thanks the UFC Fight Club, thanks Bud Light, Harley-Davidson, Tapout and Tequila Cazadores. He also says you can get four different camera angles "Beyond the Octagon" presented by Burger King tomorrow night at the UFC 100 website. Rogan's here and the Events Center is PACKED!! This might be the biggest weigh-in crowd ever.

Matt Grice v. Shannon Gugerty in a lightweight bout is up first. Gugerty at 11-3 is first up to the scale, and comes in at 156. Matt 'The Real One' Grice is 10-2. He takes off the Warrior Wear and steps on the scale to weigh in at 155 even.

'Filthy' Tom Lawlor v. CB 'The Doberman' Dollaway is our next fight. Tom Lawlor has painted JUST BLEED on his chest in white. He comes in at 184. DOllaway comes in at 186. He comes over and puts his nose about a half inch away from Lawlor. looking down at him. They exchange a friendly handshake afterwards.

TJ Grant v. Dong Hyun Kim is our third fight. Grant is a ripped 170 even. Kim steps up with an 11-0-1 record and looks very very lean and well defined. He's 171. They pose for photos.

'Irish' Jake O'Brien v. Jon 'Bones' Jones is next. O'Brien steps up first with an 11-2 record. It takes him a second to get the Tapout shorts off but when he does he weighs in at 206. Jones comes up in a black hoodie and red skull t-shirt, his abs are looking sharp, and he too weighs 206. Jones nearly walks past his opponent and looks the other way during the staredown.

Jim Miller v. Mac Danzig is our next bought at lightweight. Miller steps up at 13-2 and looks fit and ready for the fight. He's 155 even. Danzig comes up as Rogan reminds us he won Ultimate Fighter. Hasn't done much for his career since but yes, he does have that trophy. Danzig looks rock solid and muscular at 154. Friendly posedown between the two.

'The American Psycho' Stephan Bonnar v. Mark 'The Hammer' Coleman is next, our last undercard fight. Bonnar gets a cell phone call before he steps on the scale - no kidding. He weighs in at a ripped and hairy 205. Rogan introduces "the father of ground and pound" Mark Coleman, and he steps on the stage and tosses his hat off to the crowd. He adjusts his briefs, steps on the stage, and makes 205. The abs aren't perfect, but they're good for a man of his age. Dana White is wearing a "DJ Mulky Mulk/Club Creepy" t-shirt.

Jon Fitch v. Paulo Thiago is out first PPV fight. Thiago steps up at 11-0 to weigh in. He easily makes 170. Fitch gets a nice crowd pop and is quickly ready to weigh in. He steps on the scale at 170 even too. Polite pose and handshake.

Yoshihiro Akiyama v. Alan 'The Talent' Belcher. Belcher steps up first at 13-4. He belongs on a teeny-bop sop opera with that haircut. His weight is 186. Akiyama drops the camou shorts and is ready in no time. He's 185 even and Rogan calls him SEXYAMA. Belcher seems to have a little height on him in the posedown.

Michael 'The Count' Bisping v. Dan 'Hollywood' Henderson. Bisping gets a HUGE round of boos as he steps up to the stage, but stops to shake hands with Dana White first before weighing in. He makes weight at 186. Henderson at 24-7 is up next and Rogan reminds us he's the firt man in MMA to hold titles in two weight classes simultaneously. Henderson gets a nice pop as he comes in at 185 even. THe two men shake hands and then Bisping leans in like a whooping crane for the posedown.

Georges St-Pierre v. Thiago Alves is up next. Alves gets booed too on his way up the scale. His briefs leave far too little to the imagination. Alves makes 170 even for the title fight. The champion GSP is getting a pop before Rogan can even finish introducing him, and GSP signals to RAISE THE ROOF as he walks up the steps. He's 170 even too!

Joe Rogan throws us to a preview video package for Brock Lesnar and Frank Mir before we get the final weigh-in.

Frank Mir v. Brock Lesnar. The time for talking is now over. Mir strips down and poses for a second to show off his physique, getting a pop from the crowd. He steps on the scale, spreads his arms wide, flexes and weighs in at 245. Lesnar has shaved off his goatee! He throws his t-shirt out to the crowd, steps on the scale, raises his hands in the air and wiggles his fingers and weighs in at 265.

If looks could kill, the look Lesnar gives Mir during the staredown would do it. No handshake afterwards. Rogan interviews Mir and says the Nog fight was the biggest of his career up until now. "There's a thousand people still waiting to get into the weigh-ins. Nothing says it better than that. If it does, I don't know!" Rogan agrees and goes over to interview Lesnar, who gets a round of boos as he sips on his bottle of water. "It's all over but the crying baby! That's all I got to say. We'll see you tomorrow night!" He walks away and Rogan thanks us all for coming. I switched over to SportsCenter right as the weigh-ins ended and they were showing that Mir and Lesnar made weight.
