After 50 Cent challenged Floyd Mayweather Jr. to read one full page of a "Harry Potter" book, Power 105's "The Breakfast Club" released an audio of the undefeated boxer's reading a promotional "drop" for the radio station.

The unedited audio released by the New York-based morning radio show hosts Charlamagne Tha God , DJ Envy, and Angela Yee features Mayweather struggling to read a promotional drop for Power 105, Huffington Post reported.

While he has a 46-0 record as a boxer, Mayweather had difficulty reading the promo, particularly the phrase "movement to support hiring vets," New York Daily News has learned.

"I got nothing but respect for Floyd Mayweather. He's the greatest defensive fighter of all time, but I got a show to do. I gotta sell tickets too, baby," Charlamagne That God explained the station's decision to air the audio.

"Just like he likes to put on a show, I like to put on a show to. This is for our listeners' benefit," the disc jockey added.

Prior to this, 50 Cent made his ALS Ice Bucket Challenge version by pledging to donate $750,000 to a charity if Mayweather accepts the reading dare.

As a response, Mayweather simply took to Twitter to post a picture of two Mayweather Promotions, LLC checks with a caption, "Read this $72,276,000.00. God bless."

Moreover, the 37-year-old boxer is about to have a show that gives him the opportunity to discuss his wealth and boxing career as he responds to his critics' comments about his lifestyle.

After signing a six-fight contract with Showtime in 2013, Mayweather can executive produce the preview shows for his fights. 

Showtime's "All Access" series will debut its next installment on Aug. 30 featuring Mayweather's Sept. 13 rematch against Marcos Maidana.at the MGM Grand Garden in Las Vegas, Yahoo! Sports reported.

"They kind of believe. I really believe. They think they're good. I know I'm great. Still fly; still flashy. Floyd Mayweather is going to live his life like he wants to live it," Mayweather said in one segment of the debut episode.

"I am Mr. Boxing; Mr. Money Man; Mr. I'm Getting It; Mr. 500 million dollar man. When you speak boxing, you're speaking Mayweather," he added.

At one point, he also said, "I just need one percent of your trust (and) I'll earn the other 99. We can go from here. Let's make it happen."
