It's going to be sweaty and dirty, but oh-so-great-smelling later today when the old and new 'Old Spice' guys go at each other in the bathroom.

That's right: Isaiah Mustafa has accepted his successor Fabio's challenge to a duel. The two hunks, tongues squarely in cheeks, will face off at 12PM ET Tuesday, in the online showdown billed as "Mano a Mano in El Baño."

Fabio issued the challenge yesterday with the aid of two comedy duelling pistols and Mustafa quickly accepted, ridiculing his opponent's tactics: "A real man would have challenged me to a duel with a left-to-right slap across the face."

Isaiah Mustafa (aka the 'Old Spice Guy') has had a ridiculous amount of success stemming from one commercial. Of course he went on to make more of his 'The Man Your Man Could Smell Like' ads, but none struck a note in the market more than the first.

It didn't stop there. He took on the Old Spice role because he was looking for a way into the industry, and boy, did he get it. Since the ads' soaring popularity, Mustafa has appeared in several TV shows ('Ugly Betty,' 'Eli Stone,' 'NCIS,' 'Days of Our Lives' among them) and even has a role in the upcoming movie 'Horrible Bosses.'

AOL TV caught up with Mustafa at a stopover in Toronto, and he was -- where else -- on a tall ship filled with beautiful women and very tasty food. He talked about his favorite TV shows, what he thinks about all his success and how he handles this whole 'sex symbol' thing.

"I'm on a horse." If you don't recognize these words, then maybe you haven't seen the now famous 'Old Spice' ad starring Isaiah Mustafa. Two weeks ago, 'The Ellen DeGeneres Show' (weekdays, syndicated) featured a video made by Christian Lee that was a reenactment of the iconic ad. Now, the 11-year-old Lee appears on the show to do a live performance of the commercial ... with a little professional help.

It's viewer mail day on 'The Ellen DeGeneres Show' (weekdays, syndicated). And on the latest episode of the show, DeGeneres gets a fairly... unusual message from some fans. Two of her viewers -- a mother and son -- send in one of the weirdest videos that you'll ever see.

In the era of DVRs and online streaming, it's getting more and more difficult for advertisers to find a way to get viewers to sit through their commercials. One trick that always works is to make a brilliant commercial. Old Spice has managed that in a short spot that almost defies description.

On the air less than a month, we can't even tell you exactly what it is about the commercial that makes it so amazing, but we'll give a lot of the credit to the acting performance by Isaiah Mustafa, the man your man isn't.

The Primetime Creative Arts Emmy Awards -- affectionately known as the Shmemmys to Kathy Griffin fans -- has at least one more viewer this year. I will be watching the other Emmy presentation, the awards that come before the Primetime Emmys. The big one with all the major categories, musical numbers, clip montages and near-mandatory attendance by the nominees is the Emmys. The other one is the technical awards. But I will be watching for a very good reason: Neil Patrick Harris and Sarah Chalke will be co-hosting the Creative Arts Emmys this year on the E! channel, September 20.

Neil, an Emmy nominee for How I Met Your Mother, and Sarah, who is also a guest/semi-regular on Mother as well as a permanent regular on Scrubs, are a great choice for this gig. They're smart, funny, quick, attractive and maybe even unpredictable.

I mean, wouldn't it be a hoot if Neil came on stage in his Dr. Horrible gear and asked Sarah if her Hanes undies were riding up or doing their job? She should then counter and ask him about that smell, you know ... the Old Spice? Hey, maybe they should get Bruce Campbell to confront Neil about the Old Spice deal -- that was Bruce's commercial before Neil took over!
