LAS VEGAS -- The MGM Grand lobby was bustling on Friday morning, not only as a result of fans checking into the hotel, but also because even more fans were packing the pop-up shop full of official fight merchandise, where -- for the first time in fight week -- it was getting hard to move.

While many fans were buying items that featured both Floyd Mayweather and Manny Pacquiao, it was clear that it was the former that was the true merchandising king.

Hats and shirts with Floyd's trademarked terms "The Money Team," "Money, Just Make It" and "TBE" (The Best Ever) were feverishly pulled from the racks at exorbitant prices, including $88 for a leather "TMT" hat. Even socks with "Hard Work & Dedication" on them in neon green and red were being bought.

Mayweather and his company, Mayweather Promotions, unabashedly takes advantage of every opportunity to make money, but he is also smart.

Mayweather Promotions currently owns 16 trademarks and has filed for 129 more -- and that's just in the U.S.

Mayweather Promotions' merchandise arm is divided into two parts: The Money Team, which seeks to merchandise quick turnaround quotables that come out of Mayweather's mouth, and the greater Mayweather Promotions, which recently trademarked a more broad Mayweather Sports brand.

It's all overseen by Nicole Craig, who left a safe job in corporate accounting to work with Mayweather. She's now the vice president of marketing and the liaison between Mayweather and the lawyers who seek to protect the intellectual property that he is amassing.

Among the sayings Mayweather's company has filed to trademark: "TMG: The Money Girls," "The One," "May Day 411," "Damn Life I$ Good," "The Crown Jewel Of Boxing" and "Mr. My Life Is The Sh*t."

Craig says that roughly 70 percent of Mayweather sales are from the U.S., with Canada and Australia as the next two most popular countries.

Originally the only merchandise that Mayweather's team offered was "TMT" on black and white shirts. Today, that logo is being sold in almost any color imaginable. If Mayweather wins, and keeps his undefeated record, expect only more quotes to come out of his mouth, to land on merchandise and to be sold in the coming months and years.
